Contrast
Allows you to expand and
contract the distribution of pixel
densities within an image.
Higher contrast makes light
portions of an image lighter
and dark portions darker.
Lower values make light and
dark portions more neutral.
Typical settings range from
-10 (reduced contrast) to
+25 (increased contrast).
0 = no adjustment.
-80 to 80
NOTE: Values from
-100 up to -81 and
from 81 up to 100 can
be set; however, they
will be mapped to -80
and 80, respectively.
