(4.2) Upon even further research you would find out that GIMP doesn't care about that, because this is what GIMP uses LittleCMS library for :) Which coincidentally supports both 2.x and 4.x. Not 4.2, perhaps, but chances that anyone has v4.2 profiles around are floating around 0.

This can be extracted to a profile.icc if needed. Color Space tag (either standard exif or some proprietary maker note) just says that the image data is in some standard colour space (sRGB, AdobeRGB), but the profile itself is not embedded and the program must supply it on its own. Use of tags instead of embedding profile is an advantage: the image file is a bit smaller. I would assume that GIMP does not care about tags, just looks for any embedded profile. But the developers would have to confirm it. regards, Milan Knizek knizek (dot) confy (at) volny (dot) cz http://www.milan-knizek.net - About linux and photography (Czech language only) ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
