The color balance refers to the relative amounts of the three primary
colors in an image. By adjusting the color balance you can sometimes
compensate for an image with too much or too little of a color.
To adjust the color balance:
1. Click the
Color Balance
button.
The settings in the dialog box are initially set to zero for each of the
colors, indicating no change to the original image’s color balance.
2. Type a number in one or more of the
Color Levels
boxes to set a
new color level, or drag the triangles to the left or right.
Each color is paired with its complementary color, so as you drag a
triangle you are increasing a color while decreasing its
complementary color.
