Figure 4-5. Typical PLUGE Pattern for Adjusting Brightness
PLUGE patterns vary but generally consist of some combination of black, white and gray
areas against a black background. The example above includes two vertical bars and four
shaded boxes.
Select Brightness from the Main menu. Use the
or
buttons to adjust the level so that:
• The darkest black bars disappear into the background.
• The dark gray areas are barely visible.
• The lighter gray areas are clearly visible.
• The white areas are a comfortable level of true white.
• The image contains only black, gray and white (no color).
