Gamma/Pedestal/Gain

The Gamma/Pedestal/Gain effect adjusts the response curve independently for each channel. For pedestal and gain, a value of 0.0 is completely off, and a value of 1.0 is completely on.

The Black Stretch control remaps the low pixel values of all channels. Large Black Stretch values brighten dark areas. The effect is the same in all quality settings. Gamma specifies an exponent describing the shape of the intermediate curve. The Pedestal and Gain controls specify the lowest and highest attainable output value for a channel.
