Sorry if this topic had been discussed.
How does RawDigger determine the white Level and the black Level of a raw file ?
By reading the exif of the file when already calculated white/black levels are available ?
But, how about the case where they are unavailable ?
While calculating the black level with the help from optical black levels would be one of the best way, I don't have an idea on how to calculates the white level.
Could you elaborate on it ?
Many thanks in advance for your response.
