Blue Rectangle
This box shows you the region of acceptable Brightness and Contrast values. The box is
centered around the baseline settings for Brightness and Contrast, with the borders
representing the Brightness and Contrast threshold values from the VRS Administration
Utility dialog box. Valid settings must fall within the blue box. Invalid settings fall outside
the blue box borders, and they generate warnings.
Dotted Red Lines
The dotted red lines represent the current values for Brightness and Contrast. When you
have Intelligent Brightness/Contrast Adjustment enabled, the dotted red lines (along with
the slider) are automatically adjusted to reflect the “intelligent” brightness and contrast
values.
Gamma
Gamma correction relates to the contrast between the lightest and darkest areas of an image. You
can use the slider to adjust the setting, or you can make a selection from the Gamma Correct edit
box on the Clarity tab.
