The command scales the brightness values of the active layer so that the darkest point becomes black and the brightest point becomes as bright as possible, without altering its hue. This is often a “magic fix” for images that are dim or washed out. “Normalize” works on layers from RGB, Grayscale, and Indexed images.

The active layer and its Red, Green and Blue histograms after “Normalize”. The contrast is enhanced.
Histogram stretching creates gaps between the pixel columns, giving it a striped look.
