If I were to analyze or change an ICC profile embedded in an image, how should I proceed?
I'd also be glad to understand how an "end-user" is able to create these with a tristimulus colorimeter or a spectrophotometer and if/how this new profile can be added to a color capturing device (i.e. a camera).
My curiosity comes from images that were taken by a professional photographer. When I open them in GIMP, there's a pop-up referring "there is an embedded ICC profile" and if I "would like to convert the image to RGB (sRGB built-in)". I always convert all of them before using them, since the colors are slightly improved.
