Making Basic Adjustments

You can select from five gamma settings (2.0 to 2.4) or customize your own setting from your 
image or a displayed graph. Lower values will increase the contrast of dark areas, but tend to 
blur the bright areas. Higher values will darken the light areas. Gamma presets make minor 
adjustments to mid-tone values. The larger the gamma preset, the lower the midtone values. 
Changing these settings affects contrast which can be seen as a blur in bright areas.
