Section 4: PowerTool Interface
Gamma is used to fine-tune the gamma table currently in use, ranging from
1 to 3. If excess ambient light washes out the image and it becomes difficult
or impossible to see details in dark areas, lower the gamma setting to
compensate. If the image is washed out and unnatural, with excessive detail
in black areas, increase the setting. In high ambient light conditions, lower
gamma may produce better results than higher gamma. Gamma of 2.2
(default) indicates the gamma table has not been adjusted.
Manual gamma adjustment is enabled when Gamma Type is set to Custom.
