Brightness, Contrast and Gamma
Note: The Color profile option must be set to Standard mode in order to use the
Brightness, Contrast, and Gamma sliders.
To adjust the Brightness, Contrast, or Gamma values for the selected color channel,
click and move the sliders until you see the desired adjustments.
Notice that the color curve graph changes as you adjust values using these sliders,
which also reflects in the values of the Input and Output boxes displayed on the left
of the Gamma slider.
Adjusting brightness, contrast, and gamma values helps you compensate for variations
in luminance between a source image and its output on a display device. This is useful
when working with image processing applications to help provide more accurate color
reproduction of images (such as photographs) when they are displayed on your screen.
Also, many 3D-accelerated games may appear too dark to play. Increasing the
brightness and/or gamma value equally across all channels will make games appear
brighter, making them more playable.

Note: Current generation hardware overlay does not support per-component (Red,
Green, Blue) color correction, but instead exposes a single, unified color correction
channel. Therefore, if you select this setting, only the All Channels setting in the
color channels list is available. (See Color Channel)

You can adjust the Red, Green, and Blue channels by selecting each color separately
or by selecting the composite choice All channels, which is the default setting.
