For maintaining a balanced color in the surface of the images we seldom use airbrushing. First we eliminate the background, and then the surface of the photos is selected one by one to make them balanced color and clear. This airbrushing is generally used for food and non-food product. As packaging is never perfect and there may have printing error, damage, discolor for lighting etc. For this reason airbrushing is always needed for them and we, in general, use quick selection tool, clone stamp tool, color selection, path, blurring etc. to correct them.
