Removing a color cast
Some images contain color casts (imbalanced colors), which may occur during scanning or which may have existed in the original image. This photograph of the window has a blue cast. You’ll use the Auto Color feature in Photoshop 7.0 to correct this. (ImageReady does not include the Auto Color command, so this task must be done in Photoshop.)
For an illustration of color casting, see figure 3-1 in the color section.
- Choose Image > Adjustments > Auto Color.
Notice that the blue color cast is gone.
- Choose File > Save.
