Contrast
( Press
SHORT CUT:
"Contrast" increases or decreases the perceived difference between light and dark
areas of your 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).
Brightness
( Press
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.
Gamma
( Press
SHORT CUT:
"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 impossible to see details in dark
areas, lower the gamma setting to compensate. This will improve contrast while
