+!TP_LOCALLAB_GHS_BLP_TOOLTIP;Sets the Black point for a linear stretch of the image.\n * For negatives slider values, in GHS ‘normal’, shadows are raised linearly to avoid excessive noise build-up and facilitate GHS work.\n * For positives slider values, the histogram is shifted to the left. For Raw images, you can also use Raw-Tab > Raw Black Points – Dehaze,  which is more precise.\n * Contrast gained by performing the linear stretch will be evenly distributed over the image.\n\n * You can adjust a linear black point offset to either:\n  - account for noise in the deep shadows.\n  - adjust the histogram.\n\n * It is recommended to adjust these sliders before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the White point.
+!TP_LOCALLAB_GHS_BPFRAME_TOOLTIP;Sets the Black point (BP linear), White point (WP linear) and Highlight for a linear stretch of the image.\n\n * Black Point (BP linear) and White Point (WP linear) settings are only available if Stretch factor (D) is between 0.001 and 0.002 so as to not affect the histogram.\n\n * When Stretch factor is 0.002 or less, all stretch settings except for Black point and White point have no effect.\n\n * Black point (BP linear) and White point (WP linear) settings are sensitive to the general settings upstream of GHS: Highlight reconstruction, White balance and RAW processes.\n\n * To have relevant Black Point (BP linear) and White Point (WP linear) settings, the entire image must be analyzed. It is recommended to use 'Fit whole image to screen - Shortcut Alt-f'.
+!TP_LOCALLAB_GHS_B_TOOLTIP;This parameter controls how tightly focused the stretch is around the Symmetry point (SP) by changing the form of the transform itself:\n * For concentrated stretches (such as initial stretches on linear images) a large 'b' factor should be employed to focus a stretch within a histogram peak while de-focusing the stretch away from the histogram peak.\n * For adjustment of non-linear images, lower 'b' parameters should be employed to distribute contrast and brightness more evenly.\n * Large positive values of 'b' can be thought of as a histogram widener, i.e. spreading the histogram wider about the focus point, SP.\n * By contrast, lower values of 'b' tend to shift the histogram to a brighter or dimmer position without affecting its width too greatly.\n * As a general rule, the level of 'b' employed will decrease as a stretch sequence nears completion, although larger 'b' values can still be employed for precise placement of additional contrast.
+!TP_LOCALLAB_GHS_CHRO;Chromaticity Lab factor (C)
+!TP_LOCALLAB_GHS_CHRO_TOOLTIP;GHS chromaticity - compensate large stretches
+!TP_LOCALLAB_GHS_CURVE_TOOLTIP;Shows the 'S' curve generated by GHS calculations. Mainly for educational purposes.\n\n * The curve only reacts to the adjusters and cannot be modified directly.
+!TP_LOCALLAB_GHS_D;Stretch factor (D)
+!TP_LOCALLAB_GHS_D_TOOLTIP;This parameter controls the amount of stretch. If the Stretch factor is set to zero, there is no stretch. In other words, the transformation is the identity transformation.\n\n * Black Point (BP linear) and White Point (WP linear) settings are only available if Stretch factor (D) is between 0.001 and 0.002.
+!TP_LOCALLAB_GHS_GHSDIAG;GHS Curve Visualization
+!TP_LOCALLAB_GHS_HLP;White point (WP linear)
+!TP_LOCALLAB_GHS_HLP_TOOLTIP;Sets the White point for a linear stretch of the image. Any pixel with value greater than the White point input will be clipped and the data lost.\n * Contrast gained by performing the linear stretch will be evenly distributed over the image, which will be brightened. Pixels with values greater than the White point will appear white and have a value of 1.0.\n * Setting this parameter to a value greater than 1 will extend the dynamic range at the high end.\n * The 'Highlight reconstruction' method has a very strong impact on the White-point value.\n\n * It is recommended to adjust this slider before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count - Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the Black point.
+!TP_LOCALLAB_GHS_HP;Protect highlights (HP)
+!TP_LOCALLAB_GHS_HP_TOOLTIP;Sets a value above which the stretch is modified to preserve contrast in the highlights. This is done by performing a linear stretch of the data above the 'HP' level by reserving contrast from the rest of the image. Moving the HP level towards the current setting of SP increases both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to lower brightness levels while keeping the contrast and definition in the highlights. The amount of contrast reserved for the highlights is such that the continuity of the stretch is preserved.\n * This parameter must be at most 1 and no less than the Symmetry point.\n * The adjuster will automatically limits the maximum value to the Symmetry Point (SP).\n\n * Using Highlight attenuation helps to reinforce the action of Protect highlights (HP).
+!TP_LOCALLAB_GHS_INV;Inverse GHS
+!TP_LOCALLAB_GHS_INV_TOOLTIP;The inverse GHS is useful for working in negative space. It adds contrast on the far right and left of the histogram, brightening the deep shadows, darkening the bright highlights, and squeezing the histogram to the middle.\n\n * The Generalized Hyperbolic inverse transformation allows you to recover your original image, subject to mathematical precision, but you can use it for other purposes.\n\n * If the White point and Black point were changed in normal mode, they will likely need to be readjusted. The White point often needs to be readjusted lower. There is interaction between the two settings.

+!TP_LOCALLAB_GHS_LC_TOOLTIP;Slightly increases local contrast that was weakened by stretching.\nCan be completed by other tools specific to local contrast such as wavelets.\n\nWhen Stretch factor is 0.002 or less, Stretch Regularization & Midtones is disabled.
+!TP_LOCALLAB_GHS_LP;Protect shadows (LP)
+!TP_LOCALLAB_GHS_LP_TOOLTIP;Sets a value below which the stretch is modified to preserve contrast in the shadows/lowlights. This is done by performing a linear stretch of the data below the 'LP' level by reserving contrast from the rest of the image. Moving the LP level towards the current setting of SP changes both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to higher brightness levels while keeping the contrast and definition in the background. The amount of contrast reserved for the lowlights is such that the continuity of the stretch is preserved.\n * This parameter must be at least 0 and no greater than the Symmetry point.\n * The adjuster will automatically limit the maximum value to the Symmetry Point (SP).\n\n * Using Black point - negative values - when possible, allows to change both the value of Symmetry point (SP) and the action of Protect shadows (LP).
+!TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.

+!TP_LOCALLAB_GHS_SMOOTH_TOOLTIP;Smooth and soften highlight areas. Amplifies 'Protect highlights (HP)' action.
+!TP_LOCALLAB_GHS_SP;Symmetry point (SP)
+!TP_LOCALLAB_GHS_SP_TOOLTIP;The default value of 0.015 is suitable for the majority of images.\n * This is the key balance value of the GHS system.\n * Sets the focus point around which the stretch is applied - contrast will be distributed symmetrically about SP.\n * While 'b' provides the degree of focus of the stretch, SP determines where that focus is applied.\n * SP should generally be placed within a histogram peak so that the stretch will widen and lower the peak by adding the most contrast in the stretch at that point. Pixel values will move away from the SP location.

+!TP_LOCALLAB_GHS_BLP_TOOLTIP;Sets the Black point for a linear stretch of the image.\n * For negatives slider values, in GHS ‘normal’, shadows are raised linearly to avoid excessive noise build-up and facilitate GHS work.\n * For positives slider values, the histogram is shifted to the left. For Raw images, you can also use Raw-Tab > Raw Black Points – Dehaze,  which is more precise.\n * Contrast gained by performing the linear stretch will be evenly distributed over the image.\n\n * You can adjust a linear black point offset to either:\n  - account for noise in the deep shadows.\n  - adjust the histogram.\n\n * It is recommended to adjust these sliders before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the White point.
+!TP_LOCALLAB_GHS_BPFRAME_TOOLTIP;Sets the Black point (BP linear), White point (WP linear) and Highlight for a linear stretch of the image.\n\n * Black Point (BP linear) and White Point (WP linear) settings are only available if Stretch factor (D) is between 0.001 and 0.002 so as to not affect the histogram.\n\n * When Stretch factor is 0.002 or less, all stretch settings except for Black point and White point have no effect.\n\n * Black point (BP linear) and White point (WP linear) settings are sensitive to the general settings upstream of GHS: Highlight reconstruction, White balance and RAW processes.\n\n * To have relevant Black Point (BP linear) and White Point (WP linear) settings, the entire image must be analyzed. It is recommended to use 'Fit whole image to screen - Shortcut Alt-f'.
+!TP_LOCALLAB_GHS_B_TOOLTIP;This parameter controls how tightly focused the stretch is around the Symmetry point (SP) by changing the form of the transform itself:\n * For concentrated stretches (such as initial stretches on linear images) a large 'b' factor should be employed to focus a stretch within a histogram peak while de-focusing the stretch away from the histogram peak.\n * For adjustment of non-linear images, lower 'b' parameters should be employed to distribute contrast and brightness more evenly.\n * Large positive values of 'b' can be thought of as a histogram widener, i.e. spreading the histogram wider about the focus point, SP.\n * By contrast, lower values of 'b' tend to shift the histogram to a brighter or dimmer position without affecting its width too greatly.\n * As a general rule, the level of 'b' employed will decrease as a stretch sequence nears completion, although larger 'b' values can still be employed for precise placement of additional contrast.

Any pixel with value greater than the White point input will be clipped and the data lost.\n * Contrast gained by performing the linear stretch will be evenly distributed over the image, which will be brightened. Pixels with values greater than the White point will appear white and have a value of 1.0.\n * Setting this parameter to a value greater than 1 will extend the dynamic range at the high end.\n * The 'Highlight reconstruction' method has a very strong impact on the White-point value.\n\n * It is recommended to adjust this slider before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count - Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the Black point.
+!TP_LOCALLAB_GHS_HP;Protect highlights (HP)
+!TP_LOCALLAB_GHS_HP_TOOLTIP;Sets a value above which the stretch is modified to preserve contrast in the highlights. This is done by performing a linear stretch of the data above the 'HP' level by reserving contrast from the rest of the image. Moving the HP level towards the current setting of SP increases both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to lower brightness levels while keeping the contrast and definition in the highlights. The amount of contrast reserved for the highlights is such that the continuity of the stretch is preserved.\n * This parameter must be at most 1 and no less than the Symmetry point.\n * The adjuster will automatically limits the maximum value to the Symmetry Point (SP).\n\n * Using Highlight attenuation helps to reinforce the action of Protect highlights (HP).
+!TP_LOCALLAB_GHS_INV;Inverse GHS
+!TP_LOCALLAB_GHS_INV_TOOLTIP;The inverse GHS is useful for working in negative space. It adds contrast on the far right and left of the histogram, brightening the deep shadows, darkening the bright highlights, and squeezing the histogram to the middle.\n\n * The Generalized Hyperbolic inverse transformation allows you to recover your original image, subject to mathematical precision, but you can use it for other purposes.\n\n * If the White point and Black point were changed in normal mode, they will likely need to be readjusted. The White point often needs to be readjusted lower. There is interaction between the two settings.

+!TP_LOCALLAB_GHS_LP;Protect shadows (LP)
+!TP_LOCALLAB_GHS_LP_TOOLTIP;Sets a value below which the stretch is modified to preserve contrast in the shadows/lowlights. This is done by performing a linear stretch of the data below the 'LP' level by reserving contrast from the rest of the image. Moving the LP level towards the current setting of SP changes both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to higher brightness levels while keeping the contrast and definition in the background. The amount of contrast reserved for the lowlights is such that the continuity of the stretch is preserved.\n * This parameter must be at least 0 and no greater than the Symmetry point.\n * The adjuster will automatically limit the maximum value to the Symmetry Point (SP).\n\n * Using Black point - negative values - when possible, allows to change both the value of Symmetry point (SP) and the action of Protect shadows (LP).
+!TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.

+!TP_LOCALLAB_GHS_SP_TOOLTIP;The default value of 0.015 is suitable for the majority of images.\n * This is the key balance value of the GHS system.\n * Sets the focus point around which the stretch is applied - contrast will be distributed symmetrically about SP.\n * While 'b' provides the degree of focus of the stretch, SP determines where that focus is applied.\n * SP should generally be placed within a histogram peak so that the stretch will widen and lower the peak by adding the most contrast in the stretch at that point. Pixel values will move away from the SP location.

+!TP_LOCALLAB_GHS_BLP_TOOLTIP;Sets the Black point for a linear stretch of the image.\n * For negatives slider values, in GHS ‘normal’, shadows are raised linearly to avoid excessive noise build-up and facilitate GHS work.\n * For positives slider values, the histogram is shifted to the left. For Raw images, you can also use Raw-Tab > Raw Black Points – Dehaze,  which is more precise.\n * Contrast gained by performing the linear stretch will be evenly distributed over the image.\n\n * You can adjust a linear black point offset to either:\n  - account for noise in the deep shadows.\n  - adjust the histogram.\n\n * It is recommended to adjust these sliders before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the White point.
+!TP_LOCALLAB_GHS_BPFRAME_TOOLTIP;Sets the Black point (BP linear), White point (WP linear) and Highlight for a linear stretch of the image.\n\n * Black Point (BP linear) and White Point (WP linear) settings are only available if Stretch factor (D) is between 0.001 and 0.002 so as to not affect the histogram.\n\n * When Stretch factor is 0.002 or less, all stretch settings except for Black point and White point have no effect.\n\n * Black point (BP linear) and White point (WP linear) settings are sensitive to the general settings upstream of GHS: Highlight reconstruction, White balance and RAW processes.\n\n * To have relevant Black Point (BP linear) and White Point (WP linear) settings, the entire image must be analyzed. It is recommended to use 'Fit whole image to screen - Shortcut Alt-f'.
+!TP_LOCALLAB_GHS_B_TOOLTIP;This parameter controls how tightly focused the stretch is around the Symmetry point (SP) by changing the form of the transform itself:\n * For concentrated stretches (such as initial stretches on linear images) a large 'b' factor should be employed to focus a stretch within a histogram peak while de-focusing the stretch away from the histogram peak.\n * For adjustment of non-linear images, lower 'b' parameters should be employed to distribute contrast and brightness more evenly.\n * Large positive values of 'b' can be thought of as a histogram widener, i.e. spreading the histogram wider about the focus point, SP.\n * By contrast, lower values of 'b' tend to shift the histogram to a brighter or dimmer position without affecting its width too greatly.\n * As a general rule, the level of 'b' employed will decrease as a stretch sequence nears completion, although larger 'b' values can still be employed for precise placement of additional contrast.

+!TP_LOCALLAB_GHS_D;Stretch factor (D)
+!TP_LOCALLAB_GHS_D_TOOLTIP;This parameter controls the amount of stretch. If the Stretch factor is set to zero, there is no stretch. In other words, the transformation is the identity transformation.\n\n * Black Point (BP linear) and White Point (WP linear) settings are only available if Stretch factor (D) is between 0.001 and 0.002.
+!TP_LOCALLAB_GHS_GHSDIAG;GHS Curve Visualization
+!TP_LOCALLAB_GHS_HLP;White point (WP linear)
+!TP_LOCALLAB_GHS_HLP_TOOLTIP;Sets the White point for a linear stretch of the image. Any pixel with value greater than the White point input will be clipped and the data lost.\n * Contrast gained by performing the linear stretch will be evenly distributed over the image, which will be brightened. Pixels with values greater than the White point will appear white and have a value of 1.0.\n * Setting this parameter to a value greater than 1 will extend the dynamic range at the high end.\n * The 'Highlight reconstruction' method has a very strong impact on the White-point value.\n\n * It is recommended to adjust this slider before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count - Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the Black point.
+!TP_LOCALLAB_GHS_HP;Protect highlights (HP)
+!TP_LOCALLAB_GHS_HP_TOOLTIP;Sets a value above which the stretch is modified to preserve contrast in the highlights. This is done by performing a linear stretch of the data above the 'HP' level by reserving contrast from the rest of the image. Moving the HP level towards the current setting of SP increases both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to lower brightness levels while keeping the contrast and definition in the highlights. The amount of contrast reserved for the highlights is such that the continuity of the stretch is preserved.\n * This parameter must be at most 1 and no less than the Symmetry point.\n * The adjuster will automatically limits the maximum value to the Symmetry Point (SP).\n\n * Using Highlight attenuation helps to reinforce the action of Protect highlights (HP).
+!TP_LOCALLAB_GHS_INV;Inverse GHS
+!TP_LOCALLAB_GHS_INV_TOOLTIP;The inverse GHS is useful for working in negative space. It adds contrast on the far right and left of the histogram, brightening the deep shadows, darkening the bright highlights, and squeezing the histogram to the middle.\n\n * The Generalized Hyperbolic inverse transformation allows you to recover your original image, subject to mathematical precision, but you can use it for other purposes.\n\n * If the White point and Black point were changed in normal mode, they will likely need to be readjusted. The White point often needs to be readjusted lower. There is interaction between the two settings.

+!TP_LOCALLAB_GHS_LC_TOOLTIP;Slightly increases local contrast that was weakened by stretching.\nCan be completed by other tools specific to local contrast such as wavelets.\n\nWhen Stretch factor is 0.002 or less, Stretch Regularization & Midtones is disabled.
+!TP_LOCALLAB_GHS_LP;Protect shadows (LP)
+!TP_LOCALLAB_GHS_LP_TOOLTIP;Sets a value below which the stretch is modified to preserve contrast in the shadows/lowlights. This is done by performing a linear stretch of the data below the 'LP' level by reserving contrast from the rest of the image. Moving the LP level towards the current setting of SP changes both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to higher brightness levels while keeping the contrast and definition in the background. The amount of contrast reserved for the lowlights is such that the continuity of the stretch is preserved.\n * This parameter must be at least 0 and no greater than the Symmetry point.\n * The adjuster will automatically limit the maximum value to the Symmetry Point (SP).\n\n * Using Black point - negative values - when possible, allows to change both the value of Symmetry point (SP) and the action of Protect shadows (LP).
+!TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.

+!TP_LOCALLAB_GHS_SP;Symmetry point (SP)
+!TP_LOCALLAB_GHS_SP_TOOLTIP;The default value of 0.015 is suitable for the majority of images.\n * This is the key balance value of the GHS system.\n * Sets the focus point around which the stretch is applied - contrast will be distributed symmetrically about SP.\n * While 'b' provides the degree of focus of the stretch, SP determines where that focus is applied.\n * SP should generally be placed within a histogram peak so that the stretch will widen and lower the peak by adding the most contrast in the stretch at that point. Pixel values will move away from the SP location.

+TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colours based on the deltaE.

+!TP_LOCALLAB_GHS_B_TOOLTIP;This parameter controls how tightly focused the stretch is around the Symmetry point (SP) by changing the form of the transform itself:\n * For concentrated stretches (such as initial stretches on linear images) a large 'b' factor should be employed to focus a stretch within a histogram peak while de-focusing the stretch away from the histogram peak.\n * For adjustment of non-linear images, lower 'b' parameters should be employed to distribute contrast and brightness more evenly.\n * Large positive values of 'b' can be thought of as a histogram widener, i.e. spreading the histogram wider about the focus point, SP.\n * By contrast, lower values of 'b' tend to shift the histogram to a brighter or dimmer position without affecting its width too greatly.\n * As a general rule, the level of 'b' employed will decrease as a stretch sequence nears completion, although larger 'b' values can still be employed for precise placement of additional contrast.

Moving the HP level towards the current setting of SP increases both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to lower brightness levels while keeping the contrast and definition in the highlights. The amount of contrast reserved for the highlights is such that the continuity of the stretch is preserved.\n * This parameter must be at most 1 and no less than the Symmetry point.\n * The adjuster will automatically limits the maximum value to the Symmetry Point (SP).\n\n * Using Highlight attenuation helps to reinforce the action of Protect highlights (HP).

For Raw images, you can also use Raw-Tab > Raw Black Points – Dehaze,  which is more precise.\n * Contrast gained by performing the linear stretch will be evenly distributed over the image.\n\n * You can adjust a linear black point offset to either:\n  - account for noise in the deep shadows.\n  - adjust the histogram.\n\n * It is recommended to adjust these sliders before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the White point.
+!TP_LOCALLAB_GHS_BPFRAME_TOOLTIP;Sets the Black point (BP linear), White point (WP linear) and Highlight for a linear stretch of the image.\n\n * Black Point (BP linear) and White Point (WP linear) settings are only available if Stretch factor (D) is between 0.001 and 0.002 so as to not affect the histogram.\n\n * When Stretch factor is 0.002 or less, all stretch settings except for Black point and White point have no effect.\n\n * Black point (BP linear) and White point (WP linear) settings are sensitive to the general settings upstream of GHS: Highlight reconstruction, White balance and RAW processes.\n\n * To have relevant Black Point (BP linear) and White Point (WP linear) settings, the entire image must be analyzed. It is recommended to use 'Fit whole image to screen - Shortcut Alt-f'.
+!TP_LOCALLAB_GHS_B_TOOLTIP;This parameter controls how tightly focused the stretch is around the Symmetry point (SP) by changing the form of the transform itself:\n * For concentrated stretches (such as initial stretches on linear images) a large 'b' factor should be employed to focus a stretch within a histogram peak while de-focusing the stretch away from the histogram peak.\n * For adjustment of non-linear images, lower 'b' parameters should be employed to distribute contrast and brightness more evenly.\n * Large positive values of 'b' can be thought of as a histogram widener, i.e. spreading the histogram wider about the focus point, SP.\n * By contrast, lower values of 'b' tend to shift the histogram to a brighter or dimmer position without affecting its width too greatly.\n * As a general rule, the level of 'b' employed will decrease as a stretch sequence nears completion, although larger 'b' values can still be employed for precise placement of additional contrast.

Pixels with values greater than the White point will appear white and have a value of 1.0.\n * Setting this parameter to a value greater than 1 will extend the dynamic range at the high end.\n * The 'Highlight reconstruction' method has a very strong impact on the White-point value.\n\n * It is recommended to adjust this slider before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count - Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the Black point.
+!TP_LOCALLAB_GHS_HP;Protect highlights (HP)
+!TP_LOCALLAB_GHS_HP_TOOLTIP;Sets a value above which the stretch is modified to preserve contrast in the highlights. This is done by performing a linear stretch of the data above the 'HP' level by reserving contrast from the rest of the image. Moving the HP level towards the current setting of SP increases both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to lower brightness levels while keeping the contrast and definition in the highlights. The amount of contrast reserved for the highlights is such that the continuity of the stretch is preserved.\n * This parameter must be at most 1 and no less than the Symmetry point.\n * The adjuster will automatically limits the maximum value to the Symmetry Point (SP).\n\n * Using Highlight attenuation helps to reinforce the action of Protect highlights (HP).
+!TP_LOCALLAB_GHS_INV;Inverse GHS
+!TP_LOCALLAB_GHS_INV_TOOLTIP;The inverse GHS is useful for working in negative space. It adds contrast on the far right and left of the histogram, brightening the deep shadows, darkening the bright highlights, and squeezing the histogram to the middle.\n\n * The Generalized Hyperbolic inverse transformation allows you to recover your original image, subject to mathematical precision, but you can use it for other purposes.\n\n * If the White point and Black point were changed in normal mode, they will likely need to be readjusted. The White point often needs to be readjusted lower. There is interaction between the two settings.

+!TP_LOCALLAB_GHS_LP_TOOLTIP;Sets a value below which the stretch is modified to preserve contrast in the shadows/lowlights. This is done by performing a linear stretch of the data below the 'LP' level by reserving contrast from the rest of the image. Moving the LP level towards the current setting of SP changes both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to higher brightness levels while keeping the contrast and definition in the background. The amount of contrast reserved for the lowlights is such that the continuity of the stretch is preserved.\n * This parameter must be at least 0 and no greater than the Symmetry point.\n * The adjuster will automatically limit the maximum value to the Symmetry Point (SP).\n\n * Using Black point - negative values - when possible, allows to change both the value of Symmetry point (SP) and the action of Protect shadows (LP).
+!TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.

Pixel values will move away from the SP location.

+!TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.

Pixel values will move away from the SP location.

This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.

For Raw images, you can also use Raw-Tab > Raw Black Points – Dehaze,  which is more precise.\n * Contrast gained by performing the linear stretch will be evenly distributed over the image.\n\n * You can adjust a linear black point offset to either:\n  - account for noise in the deep shadows.\n  - adjust the histogram.\n\n * It is recommended to adjust these sliders before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the White point.
+!TP_LOCALLAB_GHS_BPFRAME_TOOLTIP;Sets the Black point (BP linear), White point (WP linear) and Highlight for a linear stretch of the image.\n\n * Black Point (BP linear) and White Point (WP linear) settings are only available if Stretch factor (D) is between 0.001 and 0.002 so as to not affect the histogram.\n\n * When Stretch factor is 0.002 or less, all stretch settings except for Black point and White point have no effect.\n\n * Black point (BP linear) and White point (WP linear) settings are sensitive to the general settings upstream of GHS: Highlight reconstruction, White balance and RAW processes.\n\n * To have relevant Black Point (BP linear) and White Point (WP linear) settings, the entire image must be analyzed. It is recommended to use 'Fit whole image to screen - Shortcut Alt-f'.
+!TP_LOCALLAB_GHS_B_TOOLTIP;This parameter controls how tightly focused the stretch is around the Symmetry point (SP) by changing the form of the transform itself:\n * For concentrated stretches (such as initial stretches on linear images) a large 'b' factor should be employed to focus a stretch within a histogram peak while de-focusing the stretch away from the histogram peak.\n * For adjustment of non-linear images, lower 'b' parameters should be employed to distribute contrast and brightness more evenly.\n * Large positive values of 'b' can be thought of as a histogram widener, i.e. spreading the histogram wider about the focus point, SP.\n * By contrast, lower values of 'b' tend to shift the histogram to a brighter or dimmer position without affecting its width too greatly.\n * As a general rule, the level of 'b' employed will decrease as a stretch sequence nears completion, although larger 'b' values can still be employed for precise placement of additional contrast.

Pixels with values greater than the White point will appear white and have a value of 1.0.\n * Setting this parameter to a value greater than 1 will extend the dynamic range at the high end.\n * The 'Highlight reconstruction' method has a very strong impact on the White-point value.\n\n * It is recommended to adjust this slider before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count - Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the Black point.
+!TP_LOCALLAB_GHS_HP;Protect highlights (HP)
+!TP_LOCALLAB_GHS_HP_TOOLTIP;Sets a value above which the stretch is modified to preserve contrast in the highlights. This is done by performing a linear stretch of the data above the 'HP' level by reserving contrast from the rest of the image. Moving the HP level towards the current setting of SP increases both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to lower brightness levels while keeping the contrast and definition in the highlights. The amount of contrast reserved for the highlights is such that the continuity of the stretch is preserved.\n * This parameter must be at most 1 and no less than the Symmetry point.\n * The adjuster will automatically limits the maximum value to the Symmetry Point (SP).\n\n * Using Highlight attenuation helps to reinforce the action of Protect highlights (HP).
+!TP_LOCALLAB_GHS_INV;Inverse GHS
+!TP_LOCALLAB_GHS_INV_TOOLTIP;The inverse GHS is useful for working in negative space.

Pixels with values greater than the White point will appear white and have a value of 1.0.\n * Setting this parameter to a value greater than 1 will extend the dynamic range at the high end.\n * The 'Highlight reconstruction' method has a very strong impact on the White-point value.\n\n * It is recommended to adjust this slider before the main GHS sliders to avoid clipping data.

+!TP_LOCALLAB_GHS_HP;Protect highlights (HP)
+!TP_LOCALLAB_GHS_HP_TOOLTIP;Sets a value above which the stretch is modified to preserve contrast in the highlights. This is done by performing a linear stretch of the data above the 'HP' level by reserving contrast from the rest of the image. Moving the HP level towards the current setting of SP increases both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to lower brightness levels while keeping the contrast and definition in the highlights. The amount of contrast reserved for the highlights is such that the continuity of the stretch is preserved.\n * This parameter must be at most 1 and no less than the Symmetry point.\n * The adjuster will automatically limits the maximum value to the Symmetry Point (SP).\n\n * Using Highlight attenuation helps to reinforce the action of Protect highlights (HP).
+!TP_LOCALLAB_GHS_INV;Inverse GHS
+!TP_LOCALLAB_GHS_INV_TOOLTIP;The inverse GHS is useful for working in negative space.

This is done by performing a linear stretch of the data below the 'LP' level by reserving contrast from the rest of the image. Moving the LP level towards the current setting of SP changes both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to higher brightness levels while keeping the contrast and definition in the background. The amount of contrast reserved for the lowlights is such that the continuity of the stretch is preserved.\n * This parameter must be at least 0 and no greater than the Symmetry point.\n * The adjuster will automatically limit the maximum value to the Symmetry Point (SP).\n\n * Using Black point - negative values - when possible, allows to change both the value of Symmetry point (SP) and the action of Protect shadows (LP).
+!TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.

Pixel values will move away from the SP location.

 !TP_LOCALLAB_LOGCIEQ_TOOLTIP;Activating the checkbox allows you to switch between Log encoding based on the 3 RGB channels, and Log encoding based solely on CIECAM’s brightness (Q) channel.\nUsing the Q channel instead of the RGB channels helps avoid undesirable edge effects such as hue and saturation shifts.\nHowever, the settings are more difficult to optimise because Q is unbounded and CIECAM alters the data to take into account the surround conditions, simultaneous contrast, etc.\nYou may have to adjust the following:\n   Scene conditions: Mean luminance (Yb), Whites &amp; Blacks distribution, Black Ev, White Ev.\n   Source Data Adjustments : Brightness compression, Strength.\n\nNote: when using Log encoding (Q), be careful not to activate the Disable CIECAM option in the Scene Conditions, Surround menu.

For Raw images, you can also use Raw-Tab > Raw Black Points – Dehaze,  which is more precise.\n * Contrast gained by performing the linear stretch will be evenly distributed over the image.\n\n * You can adjust a linear black point offset to either:\n  - account for noise in the deep shadows.\n  - adjust the histogram.\n\n * It is recommended to adjust these sliders before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the White point.
+!TP_LOCALLAB_GHS_BPFRAME_TOOLTIP;Sets the Black point (BP linear), White point (WP linear) and Highlight for a linear stretch of the image.\n\n * Black Point (BP linear) and White Point (WP linear) settings are only available if Stretch factor (D) is between 0.001 and 0.002 so as to not affect the histogram.\n\n * When Stretch factor is 0.002 or less, all stretch settings except for Black point and White point have no effect.\n\n * Black point (BP linear) and White point (WP linear) settings are sensitive to the general settings upstream of GHS: Highlight reconstruction, White balance and RAW processes.\n\n * To have relevant Black Point (BP linear) and White Point (WP linear) settings, the entire image must be analyzed. It is recommended to use 'Fit whole image to screen - Shortcut Alt-f'.
+!TP_LOCALLAB_GHS_B_TOOLTIP;This parameter controls how tightly focused the stretch is around the Symmetry point (SP) by changing the form of the transform itself:\n * For concentrated stretches (such as initial stretches on linear images) a large 'b' factor should be employed to focus a stretch within a histogram peak while de-focusing the stretch away from the histogram peak.\n * For adjustment of non-linear images, lower 'b' parameters should be employed to distribute contrast and brightness more evenly.\n * Large positive values of 'b' can be thought of as a histogram widener, i.e. spreading the histogram wider about the focus point, SP.\n * By contrast, lower values of 'b' tend to shift the histogram to a brighter or dimmer position without affecting its width too greatly.\n * As a general rule, the level of 'b' employed will decrease as a stretch sequence nears completion, although larger 'b' values can still be employed for precise placement of additional contrast.

Pixels with values greater than the White point will appear white and have a value of 1.0.\n * Setting this parameter to a value greater than 1 will extend the dynamic range at the high end.\n * The 'Highlight reconstruction' method has a very strong impact on the White-point value.\n\n * It is recommended to adjust this slider before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count - Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the Black point.
+!TP_LOCALLAB_GHS_HP;Protect highlights (HP)
+!TP_LOCALLAB_GHS_HP_TOOLTIP;Sets a value above which the stretch is modified to preserve contrast in the highlights. This is done by performing a linear stretch of the data above the 'HP' level by reserving contrast from the rest of the image. Moving the HP level towards the current setting of SP increases both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to lower brightness levels while keeping the contrast and definition in the highlights. The amount of contrast reserved for the highlights is such that the continuity of the stretch is preserved.\n * This parameter must be at most 1 and no less than the Symmetry point.\n * The adjuster will automatically limits the maximum value to the Symmetry Point (SP).\n\n * Using Highlight attenuation helps to reinforce the action of Protect highlights (HP).
+!TP_LOCALLAB_GHS_INV;Inverse GHS
+!TP_LOCALLAB_GHS_INV_TOOLTIP;The inverse GHS is useful for working in negative space. It adds contrast on the far right and left of the histogram, brightening the deep shadows, darkening the bright highlights, and squeezing the histogram to the middle.\n\n * The Generalized Hyperbolic inverse transformation allows you to recover your original image, subject to mathematical precision, but you can use it for other purposes.\n\n * If the White point and Black point were changed in normal mode, they will likely need to be readjusted. The White point often needs to be readjusted lower. There is interaction between the two settings.

+!TP_LOCALLAB_GHS_LP;Protect shadows (LP)
+!TP_LOCALLAB_GHS_LP_TOOLTIP;Sets a value below which the stretch is modified to preserve contrast in the shadows/lowlights. This is done by performing a linear stretch of the data below the 'LP' level by reserving contrast from the rest of the image. Moving the LP level towards the current setting of SP changes both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to higher brightness levels while keeping the contrast and definition in the background. The amount of contrast reserved for the lowlights is such that the continuity of the stretch is preserved.\n * This parameter must be at least 0 and no greater than the Symmetry point.\n * The adjuster will automatically limit the maximum value to the Symmetry Point (SP).\n\n * Using Black point - negative values - when possible, allows to change both the value of Symmetry point (SP) and the action of Protect shadows (LP).
+!TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.

+!TP_LOCALLAB_GHS_SP_TOOLTIP;The default value of 0.015 is suitable for the majority of images.\n * This is the key balance value of the GHS system.\n * Sets the focus point around which the stretch is applied - contrast will be distributed symmetrically about SP.\n * While 'b' provides the degree of focus of the stretch, SP determines where that focus is applied.\n * SP should generally be placed within a histogram peak so that the stretch will widen and lower the peak by adding the most contrast in the stretch at that point. Pixel values will move away from the SP location.

For Raw images, you can also use Raw-Tab > Raw Black Points – Dehaze,  which is more precise.\n * Contrast gained by performing the linear stretch will be evenly distributed over the image.\n\n * You can adjust a linear black point offset to either:\n  - account for noise in the deep shadows.\n  - adjust the histogram.\n\n * It is recommended to adjust these sliders before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the White point.

It is recommended to use 'Fit whole image to screen - Shortcut Alt-f'.
+!TP_LOCALLAB_GHS_B_TOOLTIP;This parameter controls how tightly focused the stretch is around the Symmetry point (SP) by changing the form of the transform itself:\n * For concentrated stretches (such as initial stretches on linear images) a large 'b' factor should be employed to focus a stretch within a histogram peak while de-focusing the stretch away from the histogram peak.\n * For adjustment of non-linear images, lower 'b' parameters should be employed to distribute contrast and brightness more evenly.\n * Large positive values of 'b' can be thought of as a histogram widener, i.e. spreading the histogram wider about the focus point, SP.\n * By contrast, lower values of 'b' tend to shift the histogram to a brighter or dimmer position without affecting its width too greatly.\n * As a general rule, the level of 'b' employed will decrease as a stretch sequence nears completion, although larger 'b' values can still be employed for precise placement of additional contrast.

+!TP_LOCALLAB_GHS_HP;Protect highlights (HP)
+!TP_LOCALLAB_GHS_HP_TOOLTIP;Sets a value above which the stretch is modified to preserve contrast in the highlights. This is done by performing a linear stretch of the data above the 'HP' level by reserving contrast from the rest of the image. Moving the HP level towards the current setting of SP increases both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to lower brightness levels while keeping the contrast and definition in the highlights. The amount of contrast reserved for the highlights is such that the continuity of the stretch is preserved.\n * This parameter must be at most 1 and no less than the Symmetry point.\n * The adjuster will automatically limits the maximum value to the Symmetry Point (SP).\n\n * Using Highlight attenuation helps to reinforce the action of Protect highlights (HP).

+!TP_LOCALLAB_GHS_INV_TOOLTIP;The inverse GHS is useful for working in negative space. It adds contrast on the far right and left of the histogram, brightening the deep shadows, darkening the bright highlights, and squeezing the histogram to the middle.\n\n * The Generalized Hyperbolic inverse transformation allows you to recover your original image, subject to mathematical precision, but you can use it for other purposes.\n\n * If the White point and Black point were changed in normal mode, they will likely need to be readjusted. The White point often needs to be readjusted lower. There is interaction between the two settings.

+!TP_LOCALLAB_GHS_LP;Protect shadows (LP)
+!TP_LOCALLAB_GHS_LP_TOOLTIP;Sets a value below which the stretch is modified to preserve contrast in the shadows/lowlights. This is done by performing a linear stretch of the data below the 'LP' level by reserving contrast from the rest of the image. Moving the LP level towards the current setting of SP changes both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to higher brightness levels while keeping the contrast and definition in the background. The amount of contrast reserved for the lowlights is such that the continuity of the stretch is preserved.\n * This parameter must be at least 0 and no greater than the Symmetry point.\n * The adjuster will automatically limit the maximum value to the Symmetry Point (SP).\n\n * Using Black point - negative values - when possible, allows to change both the value of Symmetry point (SP) and the action of Protect shadows (LP).
+!TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.

+!TP_LOCALLAB_GHS_SP_TOOLTIP;The default value of 0.015 is suitable for the majority of images.\n * This is the key balance value of the GHS system.\n * Sets the focus point around which the stretch is applied - contrast will be distributed symmetrically about SP.\n * While 'b' provides the degree of focus of the stretch, SP determines where that focus is applied.\n * SP should generally be placed within a histogram peak so that the stretch will widen and lower the peak by adding the most contrast in the stretch at that point. Pixel values will move away from the SP location.

+!TP_LOCALLAB_GHS_B_TOOLTIP;This parameter controls how tightly focused the stretch is around the Symmetry point (SP) by changing the form of the transform itself:\n * For concentrated stretches (such as initial stretches on linear images) a large 'b' factor should be employed to focus a stretch within a histogram peak while de-focusing the stretch away from the histogram peak.\n * For adjustment of non-linear images, lower 'b' parameters should be employed to distribute contrast and brightness more evenly.\n * Large positive values of 'b' can be thought of as a histogram widener, i.e. spreading the histogram wider about the focus point, SP.\n * By contrast, lower values of 'b' tend to shift the histogram to a brighter or dimmer position without affecting its width too greatly.\n * As a general rule, the level of 'b' employed will decrease as a stretch sequence nears completion, although larger 'b' values can still be employed for precise placement of additional contrast.

+!TP_LOCALLAB_GHS_HP;Protect highlights (HP)
+!TP_LOCALLAB_GHS_HP_TOOLTIP;Sets a value above which the stretch is modified to preserve contrast in the highlights. This is done by performing a linear stretch of the data above the 'HP' level by reserving contrast from the rest of the image. Moving the HP level towards the current setting of SP increases both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to lower brightness levels while keeping the contrast and definition in the highlights. The amount of contrast reserved for the highlights is such that the continuity of the stretch is preserved.\n * This parameter must be at most 1 and no less than the Symmetry point.\n * The adjuster will automatically limits the maximum value to the Symmetry Point (SP).\n\n * Using Highlight attenuation helps to reinforce the action of Protect highlights (HP).

This is done by performing a linear stretch of the data below the 'LP' level by reserving contrast from the rest of the image. Moving the LP level towards the current setting of SP changes both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to higher brightness levels while keeping the contrast and definition in the background. The amount of contrast reserved for the lowlights is such that the continuity of the stretch is preserved.\n * This parameter must be at least 0 and no greater than the Symmetry point.\n * The adjuster will automatically limit the maximum value to the Symmetry Point (SP).\n\n * Using Black point - negative values - when possible, allows to change both the value of Symmetry point (SP) and the action of Protect shadows (LP).
+!TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.

It is recommended to use 'Fit whole image to screen - Shortcut Alt-f'.
+!TP_LOCALLAB_GHS_B_TOOLTIP;This parameter controls how tightly focused the stretch is around the Symmetry point (SP) by changing the form of the transform itself:\n * For concentrated stretches (such as initial stretches on linear images) a large 'b' factor should be employed to focus a stretch within a histogram peak while de-focusing the stretch away from the histogram peak.\n * For adjustment of non-linear images, lower 'b' parameters should be employed to distribute contrast and brightness more evenly.\n * Large positive values of 'b' can be thought of as a histogram widener, i.e. spreading the histogram wider about the focus point, SP.\n * By contrast, lower values of 'b' tend to shift the histogram to a brighter or dimmer position without affecting its width too greatly.\n * As a general rule, the level of 'b' employed will decrease as a stretch sequence nears completion, although larger 'b' values can still be employed for precise placement of additional contrast.

Pixels with values greater than the White point will appear white and have a value of 1.0.\n * Setting this parameter to a value greater than 1 will extend the dynamic range at the high end.\n * The 'Highlight reconstruction' method has a very strong impact on the White-point value.\n\n * It is recommended to adjust this slider before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count - Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the Black point.
+!TP_LOCALLAB_GHS_HP;Protect highlights (HP)
+!TP_LOCALLAB_GHS_HP_TOOLTIP;Sets a value above which the stretch is modified to preserve contrast in the highlights. This is done by performing a linear stretch of the data above the 'HP' level by reserving contrast from the rest of the image. Moving the HP level towards the current setting of SP increases both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to lower brightness levels while keeping the contrast and definition in the highlights. The amount of contrast reserved for the highlights is such that the continuity of the stretch is preserved.\n * This parameter must be at most 1 and no less than the Symmetry point.\n * The adjuster will automatically limits the maximum value to the Symmetry Point (SP).\n\n * Using Highlight attenuation helps to reinforce the action of Protect highlights (HP).

+!TP_LOCALLAB_GHS_INV_TOOLTIP;The inverse GHS is useful for working in negative space.

This is done by performing a linear stretch of the data below the 'LP' level by reserving contrast from the rest of the image. Moving the LP level towards the current setting of SP changes both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to higher brightness levels while keeping the contrast and definition in the background. The amount of contrast reserved for the lowlights is such that the continuity of the stretch is preserved.\n * This parameter must be at least 0 and no greater than the Symmetry point.\n * The adjuster will automatically limit the maximum value to the Symmetry Point (SP).\n\n * Using Black point - negative values - when possible, allows to change both the value of Symmetry point (SP) and the action of Protect shadows (LP).
+!TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.

Pixel values will move away from the SP location.

For Raw images, you can also use Raw-Tab > Raw Black Points – Dehaze,  which is more precise.\n * Contrast gained by performing the linear stretch will be evenly distributed over the image.\n\n * You can adjust a linear black point offset to either:\n  - account for noise in the deep shadows.\n  - adjust the histogram.\n\n * It is recommended to adjust these sliders before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the White point.

It is recommended to use 'Fit whole image to screen - Shortcut Alt-f'.
+!TP_LOCALLAB_GHS_B_TOOLTIP;This parameter controls how tightly focused the stretch is around the Symmetry point (SP) by changing the form of the transform itself:\n * For concentrated stretches (such as initial stretches on linear images) a large 'b' factor should be employed to focus a stretch within a histogram peak while de-focusing the stretch away from the histogram peak.\n * For adjustment of non-linear images, lower 'b' parameters should be employed to distribute contrast and brightness more evenly.\n * Large positive values of 'b' can be thought of as a histogram widener, i.e. spreading the histogram wider about the focus point, SP.\n * By contrast, lower values of 'b' tend to shift the histogram to a brighter or dimmer position without affecting its width too greatly.\n * As a general rule, the level of 'b' employed will decrease as a stretch sequence nears completion, although larger 'b' values can still be employed for precise placement of additional contrast.

Pixels with values greater than the White point will appear white and have a value of 1.0.\n * Setting this parameter to a value greater than 1 will extend the dynamic range at the high end.\n * The 'Highlight reconstruction' method has a very strong impact on the White-point value.\n\n * It is recommended to adjust this slider before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count - Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the Black point.
+!TP_LOCALLAB_GHS_HP;Protect highlights (HP)
+!TP_LOCALLAB_GHS_HP_TOOLTIP;Sets a value above which the stretch is modified to preserve contrast in the highlights. This is done by performing a linear stretch of the data above the 'HP' level by reserving contrast from the rest of the image. Moving the HP level towards the current setting of SP increases both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to lower brightness levels while keeping the contrast and definition in the highlights. The amount of contrast reserved for the highlights is such that the continuity of the stretch is preserved.\n * This parameter must be at most 1 and no less than the Symmetry point.\n * The adjuster will automatically limits the maximum value to the Symmetry Point (SP).\n\n * Using Highlight attenuation helps to reinforce the action of Protect highlights (HP).

+!TP_LOCALLAB_GHS_INV_TOOLTIP;The inverse GHS is useful for working in negative space.

The White point often needs to be readjusted lower. There is interaction between the two settings.

+!TP_LOCALLAB_GHS_LP_TOOLTIP;Sets a value below which the stretch is modified to preserve contrast in the shadows/lowlights. This is done by performing a linear stretch of the data below the 'LP' level by reserving contrast from the rest of the image. Moving the LP level towards the current setting of SP changes both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to higher brightness levels while keeping the contrast and definition in the background. The amount of contrast reserved for the lowlights is such that the continuity of the stretch is preserved.\n * This parameter must be at least 0 and no greater than the Symmetry point.\n * The adjuster will automatically limit the maximum value to the Symmetry Point (SP).\n\n * Using Black point - negative values - when possible, allows to change both the value of Symmetry point (SP) and the action of Protect shadows (LP).
+!TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.

Pixel values will move away from the SP location.

For Raw images, you can also use Raw-Tab > Raw Black Points – Dehaze,  which is more precise.\n * Contrast gained by performing the linear stretch will be evenly distributed over the image.\n\n * You can adjust a linear black point offset to either:\n  - account for noise in the deep shadows.\n  - adjust the histogram.\n\n * It is recommended to adjust these sliders before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the White point.
+!TP_LOCALLAB_GHS_BPFRAME_TOOLTIP;Sets the Black point (BP linear), White point (WP linear) and Highlight for a linear stretch of the image.\n\n * Black Point (BP linear) and White Point (WP linear) settings are only available if Stretch factor (D) is between 0.001 and 0.002 so as to not affect the histogram.\n\n * When Stretch factor is 0.002 or less, all stretch settings except for Black point and White point have no effect.\n\n * Black point (BP linear) and White point (WP linear) settings are sensitive to the general settings upstream of GHS: Highlight reconstruction, White balance and RAW processes.\n\n * To have relevant Black Point (BP linear) and White Point (WP linear) settings, the entire image must be analyzed. It is recommended to use 'Fit whole image to screen - Shortcut Alt-f'.
+!TP_LOCALLAB_GHS_B_TOOLTIP;This parameter controls how tightly focused the stretch is around the Symmetry point (SP) by changing the form of the transform itself:\n * For concentrated stretches (such as initial stretches on linear images) a large 'b' factor should be employed to focus a stretch within a histogram peak while de-focusing the stretch away from the histogram peak.\n * For adjustment of non-linear images, lower 'b' parameters should be employed to distribute contrast and brightness more evenly.\n * Large positive values of 'b' can be thought of as a histogram widener, i.e. spreading the histogram wider about the focus point, SP.\n * By contrast, lower values of 'b' tend to shift the histogram to a brighter or dimmer position without affecting its width too greatly.\n * As a general rule, the level of 'b' employed will decrease as a stretch sequence nears completion, although larger 'b' values can still be employed for precise placement of additional contrast.

Pixels with values greater than the White point will appear white and have a value of 1.0.\n * Setting this parameter to a value greater than 1 will extend the dynamic range at the high end.\n * The 'Highlight reconstruction' method has a very strong impact on the White-point value.\n\n * It is recommended to adjust this slider before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count - Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the Black point.
+!TP_LOCALLAB_GHS_HP;Protect highlights (HP)
+!TP_LOCALLAB_GHS_HP_TOOLTIP;Sets a value above which the stretch is modified to preserve contrast in the highlights. This is done by performing a linear stretch of the data above the 'HP' level by reserving contrast from the rest of the image. Moving the HP level towards the current setting of SP increases both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to lower brightness levels while keeping the contrast and definition in the highlights. The amount of contrast reserved for the highlights is such that the continuity of the stretch is preserved.\n * This parameter must be at most 1 and no less than the Symmetry point.\n * The adjuster will automatically limits the maximum value to the Symmetry Point (SP).\n\n * Using Highlight attenuation helps to reinforce the action of Protect highlights (HP).
+!TP_LOCALLAB_GHS_INV;Inverse GHS
+!TP_LOCALLAB_GHS_INV_TOOLTIP;The inverse GHS is useful for working in negative space. It adds contrast on the far right and left of the histogram, brightening the deep shadows, darkening the bright highlights, and squeezing the histogram to the middle.\n\n * The Generalized Hyperbolic inverse transformation allows you to recover your original image, subject to mathematical precision, but you can use it for other purposes.\n\n * If the White point and Black point were changed in normal mode, they will likely need to be readjusted. The White point often needs to be readjusted lower. There is interaction between the two settings.

+!TP_LOCALLAB_GHS_LP;Protect shadows (LP)
+!TP_LOCALLAB_GHS_LP_TOOLTIP;Sets a value below which the stretch is modified to preserve contrast in the shadows/lowlights. This is done by performing a linear stretch of the data below the 'LP' level by reserving contrast from the rest of the image. Moving the LP level towards the current setting of SP changes both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to higher brightness levels while keeping the contrast and definition in the background. The amount of contrast reserved for the lowlights is such that the continuity of the stretch is preserved.\n * This parameter must be at least 0 and no greater than the Symmetry point.\n * The adjuster will automatically limit the maximum value to the Symmetry Point (SP).\n\n * Using Black point - negative values - when possible, allows to change both the value of Symmetry point (SP) and the action of Protect shadows (LP).
+!TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.

+!TP_LOCALLAB_GHS_SP_TOOLTIP;The default value of 0.015 is suitable for the majority of images.\n * This is the key balance value of the GHS system.\n * Sets the focus point around which the stretch is applied - contrast will be distributed symmetrically about SP.\n * While 'b' provides the degree of focus of the stretch, SP determines where that focus is applied.\n * SP should generally be placed within a histogram peak so that the stretch will widen and lower the peak by adding the most contrast in the stretch at that point. Pixel values will move away from the SP location.

For Raw images, you can also use Raw-Tab > Raw Black Points – Dehaze,  which is more precise.\n * Contrast gained by performing the linear stretch will be evenly distributed over the image.\n\n * You can adjust a linear black point offset to either:\n  - account for noise in the deep shadows.\n  - adjust the histogram.\n\n * It is recommended to adjust these sliders before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the White point.
+!TP_LOCALLAB_GHS_BPFRAME_TOOLTIP;Sets the Black point (BP linear), White point (WP linear) and Highlight for a linear stretch of the image.\n\n * Black Point (BP linear) and White Point (WP linear) settings are only available if Stretch factor (D) is between 0.001 and 0.002 so as to not affect the histogram.\n\n * When Stretch factor is 0.002 or less, all stretch settings except for Black point and White point have no effect.\n\n * Black point (BP linear) and White point (WP linear) settings are sensitive to the general settings upstream of GHS: Highlight reconstruction, White balance and RAW processes.\n\n * To have relevant Black Point (BP linear) and White Point (WP linear) settings, the entire image must be analyzed. It is recommended to use 'Fit whole image to screen - Shortcut Alt-f'.
+!TP_LOCALLAB_GHS_B_TOOLTIP;This parameter controls how tightly focused the stretch is around the Symmetry point (SP) by changing the form of the transform itself:\n * For concentrated stretches (such as initial stretches on linear images) a large 'b' factor should be employed to focus a stretch within a histogram peak while de-focusing the stretch away from the histogram peak.\n * For adjustment of non-linear images, lower 'b' parameters should be employed to distribute contrast and brightness more evenly.\n * Large positive values of 'b' can be thought of as a histogram widener, i.e. spreading the histogram wider about the focus point, SP.\n * By contrast, lower values of 'b' tend to shift the histogram to a brighter or dimmer position without affecting its width too greatly.\n * As a general rule, the level of 'b' employed will decrease as a stretch sequence nears completion, although larger 'b' values can still be employed for precise placement of additional contrast.

Any pixel with value greater than the White point input will be clipped and the data lost.\n * Contrast gained by performing the linear stretch will be evenly distributed over the image, which will be brightened. Pixels with values greater than the White point will appear white and have a value of 1.0.\n * Setting this parameter to a value greater than 1 will extend the dynamic range at the high end.\n * The 'Highlight reconstruction' method has a very strong impact on the White-point value.\n\n * It is recommended to adjust this slider before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count - Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the Black point.
+!TP_LOCALLAB_GHS_HP;Protect highlights (HP)
+!TP_LOCALLAB_GHS_HP_TOOLTIP;Sets a value above which the stretch is modified to preserve contrast in the highlights. This is done by performing a linear stretch of the data above the 'HP' level by reserving contrast from the rest of the image. Moving the HP level towards the current setting of SP increases both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to lower brightness levels while keeping the contrast and definition in the highlights. The amount of contrast reserved for the highlights is such that the continuity of the stretch is preserved.\n * This parameter must be at most 1 and no less than the Symmetry point.\n * The adjuster will automatically limits the maximum value to the Symmetry Point (SP).\n\n * Using Highlight attenuation helps to reinforce the action of Protect highlights (HP).
+!TP_LOCALLAB_GHS_INV;Inverse GHS
+!TP_LOCALLAB_GHS_INV_TOOLTIP;The inverse GHS is useful for working in negative space. It adds contrast on the far right and left of the histogram, brightening the deep shadows, darkening the bright highlights, and squeezing the histogram to the middle.\n\n * The Generalized Hyperbolic inverse transformation allows you to recover your original image, subject to mathematical precision, but you can use it for other purposes.\n\n * If the White point and Black point were changed in normal mode, they will likely need to be readjusted. The White point often needs to be readjusted lower. There is interaction between the two settings.

+!TP_LOCALLAB_GHS_LP;Protect shadows (LP)
+!TP_LOCALLAB_GHS_LP_TOOLTIP;Sets a value below which the stretch is modified to preserve contrast in the shadows/lowlights. This is done by performing a linear stretch of the data below the 'LP' level by reserving contrast from the rest of the image. Moving the LP level towards the current setting of SP changes both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to higher brightness levels while keeping the contrast and definition in the background. The amount of contrast reserved for the lowlights is such that the continuity of the stretch is preserved.\n * This parameter must be at least 0 and no greater than the Symmetry point.\n * The adjuster will automatically limit the maximum value to the Symmetry Point (SP).\n\n * Using Black point - negative values - when possible, allows to change both the value of Symmetry point (SP) and the action of Protect shadows (LP).
+!TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.

+!TP_LOCALLAB_GHS_SP_TOOLTIP;The default value of 0.015 is suitable for the majority of images.\n * This is the key balance value of the GHS system.\n * Sets the focus point around which the stretch is applied - contrast will be distributed symmetrically about SP.\n * While 'b' provides the degree of focus of the stretch, SP determines where that focus is applied.\n * SP should generally be placed within a histogram peak so that the stretch will widen and lower the peak by adding the most contrast in the stretch at that point. Pixel values will move away from the SP location.

For Raw images, you can also use Raw-Tab > Raw Black Points – Dehaze,  which is more precise.\n * Contrast gained by performing the linear stretch will be evenly distributed over the image.\n\n * You can adjust a linear black point offset to either:\n  - account for noise in the deep shadows.\n  - adjust the histogram.\n\n * It is recommended to adjust these sliders before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the White point.
+!TP_LOCALLAB_GHS_BPFRAME_TOOLTIP;Sets the Black point (BP linear), White point (WP linear) and Highlight for a linear stretch of the image.\n\n * Black Point (BP linear) and White Point (WP linear) settings are only available if Stretch factor (D) is between 0.001 and 0.002 so as to not affect the histogram.\n\n * When Stretch factor is 0.002 or less, all stretch settings except for Black point and White point have no effect.\n\n * Black point (BP linear) and White point (WP linear) settings are sensitive to the general settings upstream of GHS: Highlight reconstruction, White balance and RAW processes.\n\n * To have relevant Black Point (BP linear) and White Point (WP linear) settings, the entire image must be analyzed. It is recommended to use 'Fit whole image to screen - Shortcut Alt-f'.
+!TP_LOCALLAB_GHS_B_TOOLTIP;This parameter controls how tightly focused the stretch is around the Symmetry point (SP) by changing the form of the transform itself:\n * For concentrated stretches (such as initial stretches on linear images) a large 'b' factor should be employed to focus a stretch within a histogram peak while de-focusing the stretch away from the histogram peak.\n * For adjustment of non-linear images, lower 'b' parameters should be employed to distribute contrast and brightness more evenly.\n * Large positive values of 'b' can be thought of as a histogram widener, i.e. spreading the histogram wider about the focus point, SP.\n * By contrast, lower values of 'b' tend to shift the histogram to a brighter or dimmer position without affecting its width too greatly.\n * As a general rule, the level of 'b' employed will decrease as a stretch sequence nears completion, although larger 'b' values can still be employed for precise placement of additional contrast.

Pixels with values greater than the White point will appear white and have a value of 1.0.\n * Setting this parameter to a value greater than 1 will extend the dynamic range at the high end.\n * The 'Highlight reconstruction' method has a very strong impact on the White-point value.\n\n * It is recommended to adjust this slider before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count - Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the Black point.
+!TP_LOCALLAB_GHS_HP;Protect highlights (HP)
+!TP_LOCALLAB_GHS_HP_TOOLTIP;Sets a value above which the stretch is modified to preserve contrast in the highlights. This is done by performing a linear stretch of the data above the 'HP' level by reserving contrast from the rest of the image. Moving the HP level towards the current setting of SP increases both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to lower brightness levels while keeping the contrast and definition in the highlights. The amount of contrast reserved for the highlights is such that the continuity of the stretch is preserved.\n * This parameter must be at most 1 and no less than the Symmetry point.\n * The adjuster will automatically limits the maximum value to the Symmetry Point (SP).\n\n * Using Highlight attenuation helps to reinforce the action of Protect highlights (HP).
+!TP_LOCALLAB_GHS_INV;Inverse GHS
+!TP_LOCALLAB_GHS_INV_TOOLTIP;The inverse GHS is useful for working in negative space. It adds contrast on the far right and left of the histogram, brightening the deep shadows, darkening the bright highlights, and squeezing the histogram to the middle.\n\n * The Generalized Hyperbolic inverse transformation allows you to recover your original image, subject to mathematical precision, but you can use it for other purposes.\n\n * If the White point and Black point were changed in normal mode, they will likely need to be readjusted. The White point often needs to be readjusted lower. There is interaction between the two settings.

+!TP_LOCALLAB_GHS_LP;Protect shadows (LP)
+!TP_LOCALLAB_GHS_LP_TOOLTIP;Sets a value below which the stretch is modified to preserve contrast in the shadows/lowlights. This is done by performing a linear stretch of the data below the 'LP' level by reserving contrast from the rest of the image. Moving the LP level towards the current setting of SP changes both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to higher brightness levels while keeping the contrast and definition in the background. The amount of contrast reserved for the lowlights is such that the continuity of the stretch is preserved.\n * This parameter must be at least 0 and no greater than the Symmetry point.\n * The adjuster will automatically limit the maximum value to the Symmetry Point (SP).\n\n * Using Black point - negative values - when possible, allows to change both the value of Symmetry point (SP) and the action of Protect shadows (LP).
+!TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.

+!TP_LOCALLAB_GHS_SP_TOOLTIP;The default value of 0.015 is suitable for the majority of images.\n * This is the key balance value of the GHS system.\n * Sets the focus point around which the stretch is applied - contrast will be distributed symmetrically about SP.\n * While 'b' provides the degree of focus of the stretch, SP determines where that focus is applied.\n * SP should generally be placed within a histogram peak so that the stretch will widen and lower the peak by adding the most contrast in the stretch at that point. Pixel values will move away from the SP location.

For Raw images, you can also use Raw-Tab > Raw Black Points – Dehaze,  which is more precise.\n * Contrast gained by performing the linear stretch will be evenly distributed over the image.\n\n * You can adjust a linear black point offset to either:\n  - account for noise in the deep shadows.\n  - adjust the histogram.\n\n * It is recommended to adjust these sliders before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the White point.

It is recommended to use 'Fit whole image to screen - Shortcut Alt-f'.
+!TP_LOCALLAB_GHS_B_TOOLTIP;This parameter controls how tightly focused the stretch is around the Symmetry point (SP) by changing the form of the transform itself:\n * For concentrated stretches (such as initial stretches on linear images) a large 'b' factor should be employed to focus a stretch within a histogram peak while de-focusing the stretch away from the histogram peak.\n * For adjustment of non-linear images, lower 'b' parameters should be employed to distribute contrast and brightness more evenly.\n * Large positive values of 'b' can be thought of as a histogram widener, i.e. spreading the histogram wider about the focus point, SP.\n * By contrast, lower values of 'b' tend to shift the histogram to a brighter or dimmer position without affecting its width too greatly.\n * As a general rule, the level of 'b' employed will decrease as a stretch sequence nears completion, although larger 'b' values can still be employed for precise placement of additional contrast.

Pixels with values greater than the White point will appear white and have a value of 1.0.\n * Setting this parameter to a value greater than 1 will extend the dynamic range at the high end.\n * The 'Highlight reconstruction' method has a very strong impact on the White-point value.\n\n * It is recommended to adjust this slider before the main GHS sliders to avoid clipping data. A very low Stretch factor (D) value (0.001 by default) is recommended for performing this adjustment.\n * The label 'Clipped pixel count - Shadows:x Highlights=y' shows you the number of pixels that would be clipped without adjusting the two sliders.\n * The label Pixel values - Darkest:w Lightest:z shows you the minimum and maximum values in the range [0, 1].\n\n * In ‘Inverse GHS’ mode the behavior is reversed and there are possible interactions with the Black point.
+!TP_LOCALLAB_GHS_HP;Protect highlights (HP)
+!TP_LOCALLAB_GHS_HP_TOOLTIP;Sets a value above which the stretch is modified to preserve contrast in the highlights. This is done by performing a linear stretch of the data above the 'HP' level by reserving contrast from the rest of the image. Moving the HP level towards the current setting of SP increases both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to lower brightness levels while keeping the contrast and definition in the highlights. The amount of contrast reserved for the highlights is such that the continuity of the stretch is preserved.\n * This parameter must be at most 1 and no less than the Symmetry point.\n * The adjuster will automatically limits the maximum value to the Symmetry Point (SP).\n\n * Using Highlight attenuation helps to reinforce the action of Protect highlights (HP).
+!TP_LOCALLAB_GHS_INV;Inverse GHS
+!TP_LOCALLAB_GHS_INV_TOOLTIP;The inverse GHS is useful for working in negative space. It adds contrast on the far right and left of the histogram, brightening the deep shadows, darkening the bright highlights, and squeezing the histogram to the middle.\n\n * The Generalized Hyperbolic inverse transformation allows you to recover your original image, subject to mathematical precision, but you can use it for other purposes.\n\n * If the White point and Black point were changed in normal mode, they will likely need to be readjusted. The White point often needs to be readjusted lower. There is interaction between the two settings.

+!TP_LOCALLAB_GHS_LP;Protect shadows (LP)
+!TP_LOCALLAB_GHS_LP_TOOLTIP;Sets a value below which the stretch is modified to preserve contrast in the shadows/lowlights. This is done by performing a linear stretch of the data below the 'LP' level by reserving contrast from the rest of the image. Moving the LP level towards the current setting of SP changes both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to higher brightness levels while keeping the contrast and definition in the background. The amount of contrast reserved for the lowlights is such that the continuity of the stretch is preserved.\n * This parameter must be at least 0 and no greater than the Symmetry point.\n * The adjuster will automatically limit the maximum value to the Symmetry Point (SP).\n\n * Using Black point - negative values - when possible, allows to change both the value of Symmetry point (SP) and the action of Protect shadows (LP).
+!TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.

Pixel values will move away from the SP location.

 TP_LOCALLAB_GHS_INV;Inverse GHS
 TP_LOCALLAB_GHS_INV_TOOLTIP;The inverse GHS is useful for working in negative space. It adds contrast on the far right and left of the histogram, brightening the deep shadows, darkening the bright highlights, and squeezing the histogram to the middle.\n\n * The Generalized Hyperbolic inverse transformation allows you to recover your original image, subject to mathematical precision, but you can use it for other purposes.\n\n * If the White point and Black point were changed in normal mode, they will likely need to be readjusted. The White point often needs to be readjusted lower. There is interaction between the two settings.

+TP_LOCALLAB_GHS_LC_FRAME;Stretch Regularization & Midtones
+TP_LOCALLAB_GHS_LC_TOOLTIP;Slightly increases local contrast that was weakened by stretching.\nCan be completed by other tools specific to local contrast such as wavelets.\n\nWhen Stretch factor is 0.002 or less, Stretch Regularization & Midtones is disabled.
+TP_LOCALLAB_GHS_LP;Protect shadows (LP)
+TP_LOCALLAB_GHS_LP_TOOLTIP;Sets a value below which the stretch is modified to preserve contrast in the shadows/lowlights. This is done by performing a linear stretch of the data below the 'LP' level by reserving contrast from the rest of the image. Moving the LP level towards the current setting of SP changes both the scope (range) and the amount of this contrast reservation. The net effect is to push the overall stretch to higher brightness levels while keeping the contrast and definition in the background. The amount of contrast reserved for the lowlights is such that the continuity of the stretch is preserved.\n * This parameter must be at least 0 and no greater than the Symmetry point.\n * The adjuster will automatically limit the maximum value to the Symmetry Point (SP).\n\n * Using Black point - negative values - when possible, allows to change both the value of Symmetry point (SP) and the action of Protect shadows (LP).
+TP_LOCALLAB_GHS_METHOD_TOOLTIP;The Generalized Hyperbolic Stretch (GHS) process allows you to transform the values of pixels in your image to improve the representation of the underlying data for human visualisation.\nThe generalized hyperbolic equations used in the GHS process have five main parameters. This allows significant flexibility in designing the "shape" of the transformation.\n\nTypical uses of pixel intensity transformations include:\n * Initial stretch of pixel data from linear state.\n * Addition of contrast to key areas of the image.\n * Overall brightening or darkening of the image.\n * Adjustment of the image dynamic range.\n * Adjustment of pixel data in RGB Luminance, RGB standard, Luminance - chromaticity (Lab/Lch), Luminance (HSL), Saturation (HSL), or Hue (HSL) channels.\n\n * For a better results, you can proceed in several steps, creating 2 or more RT-spots each superimposed with the GHS tool. For each of the RT-Spots, the Symmetry point (SP) base value will be different. Use the histogram peak to position the SP value.\n * For example, you can start the system in RGB mode (1st Spot), then the 2nd Spot in RGB mode with a different SP, and the 3rd in Saturation or Hue mode.\n * You can mix RT-spots in 'Normal' mode and 'Inverse' mode to restore contrast balance.\n * Full Image allows you to limit the effect to specific colors based on the deltaE.
+TP_LOCALLAB_GHS_MID;Midtones
+TP_LOCALLAB_GHS_MID_TOOLTIP;Adjusts midtone balance after GHS transformation.\n Can be used to rebalance the midtones of the image after stretching.\n\nWhen Stretch factor is 0.002 or less, Stretch Regularization & Midtones is disabled

+TP_LOCALLAB_GHS_SMOOTH;Highlight attenuation
+TP_LOCALLAB_GHS_SMOOTH_TOOLTIP;Smooth and soften highlight areas. Amplifies 'Protect highlights (HP)' action.
+TP_LOCALLAB_GHS_SP;Symmetry point (SP)
+TP_LOCALLAB_GHS_SP_TOOLTIP;The default value of 0.015 is suitable for the majority of images.\n * This is the key balance value of the GHS system.\n * Sets the focus point around which the stretch is applied - contrast will be distributed symmetrically about SP.\n * While 'b' provides the degree of focus of the stretch, SP determines where that focus is applied.\n * SP should generally be placed within a histogram peak so that the stretch will widen and lower the peak by adding the most contrast in the stretch at that point. Pixel values will move away from the SP location.
