Corel Painter includes various options for equalizing images. Equalizing involves increasing the contrast by resetting the darkest and lightest points and then evenly distributing the values across those two points.
You can produce an equalizing effect by automatically or manually adjusting the black and white points in an image.
You can also equalize an image by using the Equalize effect. This effect allows you to adjust contrast, adjust black and white points, and distribute the brightness levels throughout the entire range of available levels. In addition, you can equalize an image by creating a histogram showing the number of pixels for each brightness level value and then adjusting those values. The Equalize effect also allows gamma adjustment, which lightens or darkens an image without changing highlights or shadows.
