I've become a great fan of Dan Margulis and his books on color correction. See Photoshop Professional and Photoshop Lab Color. (BTW, while the books are aimed at PS users, I've found them very good for a basic understanding.) Almost all of his ideas can be implemented in the Gimp, except for his use of the luminosity blending mode in layers. Value blending mode is related, but it really doesn't work as well the luminosity mode does in PS. I can see Gimp calculates luminosity, but I don't know if this is the same "luminosity" PS calculates, or, for that matter, how it's actually used as a "blending mode". In any event, I'd like to put it on the wish list for 3.0 (dare I hope for 2.8?) sean _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
