2. Improve Portraits: Vibrance has built-in protection to avoid oversaturating skin tones. The software detects the tonal range of skin tones, and does not add saturation to these areas. In Photo B, Saturation was used on the left side, which affected all color values including skin tones, creating unnatural, undesirable tones. Vibrance, used on the right side, saturated various colors, including the eye makeup and the coat, without unnaturally altering skin tones.
