But the term “light-related” also includes burning, dodging, highlight detail, shadow detail, curves, levels, white balance, color balance, tonal relationships in monochrome (black-and-white) photographs, converting a film negative to a positive, converting a color photo to black-and-white, and various other light-related items.
