ADOBE PHOTOSHOP CS2 
User Guide 
Select the Colorize option. If the foreground color is black or white, the image is converted to a red hue (0˚). If the 
foreground color is not black or white, the image is converted to the hue of the current foreground color. The 
lightness value of each pixel does not change. 
(Optional) Use the Hue slider to select a new color. Use the Saturation and Lightness sliders to adjust the 
saturation and lightness of the pixels. 
To use the Color Balance command 
The Color Balance command changes the overall mixture of colors in an image for generalized color correction. 
Make sure the composite channel is selected in the Channels palette. This command is available only when you’re 
viewing the composite channel. 
Do one of the following: 
• 
Choose Image > Adjustments > Color Balance. 
• 
Choose Layer > New Adjustment Layer > Color Balance. Click OK in the New Layer dialog box.
Select Shadows, Midtones, or Highlights to select the tonal range in which you want to focus the changes.
(Optional) Select Preserve Luminosity to prevent changing the luminosity values in the image while changing the
color. This option maintains the tonal balance in the image.
Drag a slider toward a color that you want to increase in the image; drag a slider away from a color that you want
to decrease in the image.
The values above the color bars show the color changes for the red, green, and blue channels. (For Lab images, the
values are for the A and B channels.) Values can range from -100 to +100. 
To change the color balance using the Photo Filter command 
The Photo Filter command mimics the technique of putting a colored filter in front of the camera lens to adjust the 
color balance and color temperature of the light transmitted through the lens and exposing the film. The Photo Filter 
command also lets you choose a color preset to apply a hue adjustment to an image. If you want to apply a custom 
color adjustment, the Photo Filter command lets you specify a color using the Adobe Color Picker. 
Do one of the following: 
• 
Choose Image > Adjustments > Photo Filter. 
• 
Choose Layer > New Adjustment Layer > Photo Filter. Click OK in the New Layer dialog box.
