dcraw provides the default values used by RawTherapee, but often provides too high white levels, and only provides a

is rendered in a pink/magenta color rather than white it usually means that the white level constant is too high. You can

By conservative values we mean that if you see a white level of most often 15760 and occasionally 15759 (i.e. very small
|
||||
variation of white level which is a common case), you set the white level around 50-100 14-bit units below or
|
||||
10-20 12-bit units. Say at 15700 in this example, or 4080 instead of 4095 for 12-bit raws. This way we get a little margin
|

from noise and camera variation. Since sensor raw values are linear, you lose, for example,

from noise and camera variation. Since sensor raw values are linear, you lose, for example,
|
||||
log2(1-50/15760) = -0.005 stops of detail, i.e. irrelevant. Thus it is better to provide RawTherapee with knowledge
|
||||
where the image clips rather than keeping that last 0.005 stop of highlight information and risking that clipping will
|
||||
not be detected properly.
|
||||
|
||||
It is very usual for white level to be a bell distribution instead of a candle when the camera applies long exposure
|
||||
noise reduction (LENR) by subtracting a black frame and/or when the system is destabilized due to temperature. Some models have
|
||||
always a bell distribution at WL. If you have a fuzzy white level look at the linear histogram; you will probably see a

always a bell distribution at WL. If you have a fuzzy white level look at the linear histogram; you will probably see a

normal/Gaussian distribution (bell shape) noise peak at clipping and probably also a peak at a hard raw data clip level
|
||||
usually at or close to a power of two - 1, such as 4095 or 16383. Then you pick a value just before the bell shape
|
||||
rises, i.e. to the left of the bell meaning that you cut away the whole fuzzy noise peak. If a little of the starting edge
