Sometimes when I look at some commercial/fashion photos or posters (here for example: http://www.dominickphoto.com), I want to know how the color toning was done. (sorry, I don't know if "color toning" - or "color grading"? - is the right term - english is not my first language). I know that curves and color balance was propably used, but I want to learn more about adjusting color in portraits in this way. Can you give me some insights? Can somebody recommend me some (preferaby internet) guide/tutorial? Thanks!
