Imager Color Correct - Arnold User Guide
Use the color correct imager to adjust saturation, contrast, gamma, gain and offset for the whole luminance range, or only for shadows, midtones, or highlights.
Input
Input points to the previous imager operation in the chain (so that you can stack them and apply multiple operations serially).
Enable
Enables this imager.
Layer Selection
A glob pattern or regular expression that selects the AOVs processed by the imager. The selection can be multiple selections joined by:
or(union)and(intersection)not(negation)and not(exclusion)()for nested selections
By default, glob matching is used unless the selection is in a regex quotes (r'<my_regex>'). For example:
specular or diffusenot r'sss_(direct|indirect)r'color_(mask1|mask2)' or r'mask[34]'
