Brightness/Contrast

The Brightness/Contrast adjustment allows to make simple adjustments to the tonal range of an image. Watch our video tutorial to learn more about the Brightness/Contrast adjustment.

Select the command Image -> Adjustment -> Brightness/Contrast to display the adjustment parameters in the Settings Panel.

You can also use an adjustment layer Brightness/Contrast (command Layers -> New -> Adjustment Layer -> Brightness/Contrast) which will affect all the underlying layers without changing their content.

Parameters:

Brightness (-200..200). The parameter adjusts the brightness of an image. By increasing the value, all pixels become lighter; by decreasing the value the image appears darker.

Brightness = -50

Brightness = 50

Contrast (-200..200). The parameter increases (at values greater than 0) or decreases (at values less than 0) the difference between light and dark areas of an image.

Contrast = -50

Contrast = 50

Fixed Preview Area check-box. If the check-box is enabled, the parameter changes are displayed in the small area bounded by the dotted line. If the check-box is disabled, the changes are shown in the area visible in the Image Window.
