He describes a ratio of C-M-Y which can be used to numerically adjust skin tone in an image. This ratio appears to be based on PSes internal CMY(K) colour profile and thus (I've since discovered) probably has no bearing on anything! Jacek: My suggestion would be to use a calibrated monitor and an image which has been curve adjusted in PS to get the skin tones numerically "correct", and then to learn to do it by eye. I think that the numerical method is good for starting out, but after a while you should be adjusting to what *you* want, not what the numbers suggest! :-) Jon _______________________________________________ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
