Making Basic Adjustments 31
Adjusting the Gamma Setting
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.
