Equalize: This option adjusts the brightness of colors across the active image so that the histogram for the value channel is as nearly as possible flat, that is, so that each possible brightness value appears at about the same number of pixels as each other value. Sometimes Equalize works wonderfully at enhancing the contrasts in an image. Other times it gives garbage. It is a very powerful operation, which can either work miracles on an image or destroy it.
