VRS Getting Started Guide
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.
