Brightness
Bright
Press to increase or decrease the amount of black in the image. Use
Bright
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 3.6,
Adjusting the Image (Image Settings subsection).
NOTE: Always adjust brightness before contrast.
Contrast

Contra st
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 3.6,
Adjusting the Image (Image Settings subsection).
Gamma
Gam m a
NOTE: This is the same as "Gamma" in the Image Settings Menu.
"Gamma" determines what 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 colors and grays. Thus, unlike brightness and
contrast settings 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 2.2 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.
