There are two ways to adjust the colors in an image. The first method is to choose a command from the Image > Adjustments submenu. This method permanently alters the pixels in the active layer.
The second method is to use an adjustment layer. Adjustment layers let you experiment with color and tonal adjustments without permanently modifying the pixels in the image. The color and tonal changes reside within the adjustment layer, which acts as a veil through which the underlying image layers appear. You must use Photoshop to create and edit adjustment layers; however, you can view existing adjustment layers in ImageReady.
