Figure 4-2. 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 Picture Adjust menu. Using the left- and right-arrow ( ) buttons, adjust the brightness 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).
