The Luminosity Editor
Although it affects brightness rather than color, editing luminos-
ity has a similar effect to editing the master curve in the Curves
palette. Steepening the curve by, for example, lowering the maxi-
mum value for input and raising the minimum value increases the
difference between light and dark areas of the image, increasing
contrast. Changing the gray point alters the brightness of mid-
tones while preserving details in highlights and shadows. You can
also edit specific portions of the curve for more precise control.
