Histogram Equalization

Histogram Equalization command redistributes the brightness values of the pixels of an image so that they more evenly represent the entire range of brightness levels. When the user applies this command, PhotoImpro finds the brightest and darkest values in the composite image and remaps them so that the brightest value represents white and the darkest value represents black. PhotoImpro then attempts to equalize the brightness i.e. distributes the intermediate pixel values evenly throughout the grayscale.

To use the Histogram Equalization command:

Choose Image > Adjustments > Equalize
