Adjusting the gamma curve
You can adjust the gamma curve on your display to match images you acquire
or images you are exporting, whichever is appropriate. For example, most
scanners use a gamma value of 1.0, most computer displays (including the
Macintosh) use a gamma value of 1.8, and video-editing equipment (such as
HDTV) uses a gamma value of 2.2.
