Now we've gone through adjust the R, G and B tones individually, we can see how subtle the changes can be made to the overall image. whenever i process an image, i combine the use of RGB curve enhancement together (see example) to get my desired color tone. After processing used each individual curve, i realized that a colder tone would suit the image better and enhance the garment's color. An important thing to remember is that your color processing should always suit the theme of the shoot and help enhance the mood of product within the photograph, and not overpower it.
