| Gamma:
A simple explanation... |
| In computer imaging
and display screens "gamma" refers to the degree
of contrast between the midlevel gray values of an image.
The technical explanations of gamma are irrelevant here —
the visual effect of changing gamma values is easy to see.
If you own a copy of Adobe ImageReady, open an image with
an average range of colors and contrasts and use the "Image:
Adjust: Gamma" control to change the gamma settings.
Images will change noticeably with even minor
changes in gamma settings. Gamma considerations are particularly
important if you are displaying images with very long gray
scales (such as medical diagnostic images and fine black-and-white
photography) or images in which the exact color values are
critical (such as works of art and clinical medical photographs):
