I have quite a scpecific question concerning the Tone Response Curves formula :
Luminance = Contrast x (value)^(gamma) + black level[/code] I have a good idea of what the black leve term means, but I have more problems with the Contrast term : does it correspond to the contrast given by the formula [code] (Lmax-Lmin) / Lmin
or is it calculated in an other way?
I have some measures I have tried to match using these equations, but it did not work properly.
I would be very thankful if someone could help me a bit, because I can’t seem to find the answer on the internet
Thanks in advance.
