Color balance
The Color Balance command lets you adjust color in shadows, midtones, and highlights. You can use
it with paint objects in CMYK Color or RGB Color modes.
To use the Color Balance command:
1. Select one or more paint objects to adjust all the images. You can select an area in one image
in edit mode to adjust the selected area only. If you don’t make a selection, the entire image
in edit mode is affected.
2. Choose Image | Adjust | Color Balance.
3. Click Shadows, Midtones, or Highlights to select the tonal range you want to adjust. You can
set the color levels independently for each tonal range.
4. Drag a slider toward a color label to increase the amount of that color. The letters indicate
the primary color values: Cyan, Red, Magenta, Green, Yellow, and Blue.
When you increase the amount of a color, you also reduce its inverse, which is the color
labeled at the other end of the slider.
5. Click Preview to preview the color adjustments. Preview is only available if a single paint
object is in edit mode.
6. Click OK to apply the settings.
Levels
You can adjust the brightness of shadows, highlights, or midtones by using the Levels command.
Brightness values range from 0 (black) to 255 (white). For colored pixels, brightness is the
brightness value in each color channel.
The Levels command works with all image modes except Black & White and Indexed.
To adjust levels:
1. Select a paint object to adjust. You can select an area in the image to adjust the selected area
only.
