Hi milc, thanks for your answer. These tutorials explain how to modify the Saturation/Brightness/Contrast, buy I'm triying to get this attributes. Do you know how can I do it?

Thanks very much!

Ggoogling "calculate brightness rgb" and "calculate saturation image" (and the like) will take you straight to the general arithmetic answers. For calculation in Jitter, how about jit.rgb2hsl and jit.3m?
