ICC gamut mapping
The ICC
http://www.color.org has four gamut rendering intents colorimetric, including light source conversion as some semblance of appearance consideration, and no shrinking of the output gamut to include out of gamut colors, out of gamut colors are clipped to the output gamut absolute colorimetric, no light source conversion, no output gamut shrinking, for measurement use cases primarily I guess saturation, where the output gamut is shrunk considering saturation to include colors mapped to the output space that are out of gamut with the saturation maintained over color considerations perceptual, where the output gamut is shrunk to include out of gamut colors in a pleasant appearance based on an ideal print gamut, PRM(G) http://www.color.org/v4_prmg.xalter wouldn't it be better to provide the user more choices on perceptual rendering based on different outputs? transparencies and translucencies have a much bigger gamut than a print and are created digitally now too I don't remember the math terms used for gamut construction and conversion, I used to work/edit with MATLAB scripts from the scientists that did this but I was just a systems engineer -- Dale |
