Image - Brightness / Contrast

Allows alteration of brightness and contrast of selected pixels or over the entire RGB or RGBa image if no pixels have been selected. Brightness makes the image lighter or darker overall, while Contrast either emphasizes or de-emphasizes the difference between lighter and darker regions. See the Colors as Hue, Saturation and Brightness topic for more information on brightness.



Increase or decrease the brightness of pixels. Low brightness will result in dark tones while high brightness will result in lighter, pastel tones.


Increase or decrease contrast. Increasing contrast increases the apparent difference in lightness between lighter and darker pixels.

These commands are also available on the Transform Toolbar for images as the Brightness and Contrast transform operators. However, when used from the transform toolbar the effects are immediate with no preview possible.
