Contrast
SHORT CUT:
"Contrast" increases or decreases the perceived difference between light and dark
areas of the image (0-100). For best results, keep close to 50. If contrast is set too
high, the light parts of the image lose detail and clarity. If set too low, the light areas
will not be as bright as they could be and the overall image will be dim. For best
results, start with a low value and increase so that whites remain bright but are not
distorted or tinted, and that light areas do not become white (i.e., are "crushed").
NOTE: If the environment lighting changes, an adjustment of Gamma is
recommended (see below).

Bright
SHORT CUT:
"Brightness" increases or decreases the amount of black in the image (0-100). For
best results, keep close to 50. Start with a high value and decrease so that dark areas
do not become black (i.e., are "crushed"). Conversely, high brightness changes black
to dark gray, causing washed-out images.
NOTE: Brightness should be adjusted before contrast, as Brightness setting affects
the contrast setting.
Gamma

SHORT CUT: Gamma
"Gamma" is a global setting that determines what gray shades are displayed between
minimum input (black) and maximum input (white) for all signals. A good gamma
setting helps to optimize blacks and whites while ensuring smooth transitions for the
"in-between" values utilized in other colors.
Thus, unlike "Brightness" and "Contrast"
controls, the overall tone of your images can
be lightened or darkened without changing
the extremes, and all images will be more
vibrant while still showing good detail in
dark areas.
Gamma is used to fine tune the gamma table currently in use, ranging from 1 – 3 (2.5
= default). If excess ambient light washes out the image and it becomes difficult or
