File browser thumbnails for raw images start with a minimally-processed
images. These images are cached and image adjustments are applied on
top. The black level is "baked-into" the cached image. Therefore, to
reflect the black level adjustments in the thumbnail, one of two options
are required:
1. Cache an image before the black level is applied and process the
black level on top of this image.
2. Recreate the base image with the new black level and cache it.
The first option yields better performance when the user changes the
black level. However, it requires other base adjustments to be applied
every time, such as the camera multipliers. The second option requires
the base image to be recreated every time the black level is changed.
This commit implements the second option. It minimizes code changes, and
therefore possible bugs. It does add a performance penalty when the
black level changes, but the black level adjustment is rarely used.
Use LCMS to convert values back into L*a*b*. The pipette buffer has the
output or working profile applied with LCMS. Performing the inverse
operation fixes the incorrect values shown in the navigator, histogram
indicator bars, and lockable color pickers.
Place it between the shadows curve (black and shadow compression) and
DCP tone curve and look table. Moving it after exposure makes it
possible to easily adjust the exposure to the ball-park range before
applying the tone equalizer. Keeping it before the tone curves allows it
to affect the image before clipping occurs.
