Fully Utilizing Photo CD Images Article No. 4 - PhotoYCC Color Encoding and Compression Schemes http://www.kodak.com/global/en/professional/products/storage/pcd/techInfo/pcd-045.jhtml One other thing I should mention: the profile I've created for PYCC is only in the domain 0 <= R, G, B <= 1 for the CCIR-709 Reference Primaries. In theory negative values and values greater than 1 are possible for colours outside the CCIR-709 gamut but this would make the profile either larger or less accurate and in most cases these extreme values will never occur. Also, my profile does not give the same exact values as Kodak's. Their profile seems to be rather nonlinear and has some tonal shifts. The only way I could possibly replicate that profile would be to copy their curves, and that would make my profile a derived work, which I'm not willing to do. I believe that my profile does meet the published specification. Andrew.
