Contrast
Press
Contrast
to change the amount of white in your images. Use keys until
you reach the desired level of contrast—for best results, start low and increase so that
whites remain bright but are not distorted or tinted, and that light areas do not
become white (i.e., “crushed”). Conversely, low contrast causes dim images. See
3.5,
Adjusting the Image (Image Settings subsection) .
Brightness
Press
Bright
to increase or decrease the amount of black in the image. Use
keys until you reach the desired level of contrast—for best results, start high and
decrease so that dark areas do not become black (i.e., “crushed”). Conversely, overly
high brightness changes black to dark gray, causing washed-out images. See
3.5,
Adjusting the Image (Image Settings subsection) .
Gamma
“Gamma” determines how gray shades are displayed between minimum input (black)
and maximum input (white) for a given amount of signal. The proper setting helps
maintain optimized blacks and whites while ensuring a smooth transition for the “in-
between” values utilized in grays. Unlike brightness and contrast controls, the
overall tone of an image can be lightened or darkened without changing the two
extremes, and your images will be more vibrant yet with good detail in dark areas.
The normal gamma setting of 2.22 is correct for most signals and conditions. 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 ratio while maintaining good details for blacks.
