Using Color Channels

When an image uses one of the color modes that has color (for example, not bitmap or grayscale mode), Photoshop displays each color to be displayed or printed as a separate channel. You can work with the image information for a particular channel to edit only that color in the image. This section shows you how to display a channel and gives an example of working with channel content.

NOTE

Bitmap, grayscale, duotone, and indexed images have a single channel. You can add more channels, called alpha channels, to any type of image but bitmaps. (See “Adding an Alpha Channel” in the next chapter to learn how to add an alpha channel.) The alpha channels you add can hold masks or add separate colors to be printed in the image.
