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 (Picture Adjustments
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 (Picture Adjustments
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 when using the Gamma control.
