Brightness and Contrast tool

The Brightness & Contrast tool lets you control the brightness
and contrast levels of the entire image. Increasing the brightness
makes all tones in the image lighter. Contrast, on the other hand, is
the range between the darkest and lightest shades in the image,
and increasing the contrast makes greater separation between the
darkest and lightest areas of the image.
