Chapter 5: Painting And Image Editing
Multichannel image mode
Multichannel image mode lets you work with multiple channels of grayscale information for a
grayscale image. In multichannel mode, each channel contains lightness values as in other image
modes, but the values do not relate to color components.
When you convert an image to Multichannel mode, the image data does not change; e.g., if you
convert an RGB Color mode image to Multichannel mode, the Red, Green, and Blue channels retain the
same pixel information, but the channels no longer represent color pixels. The channels in
Multichannel mode are labeled numerically (#1, #2, and so on) in the Channels palette.
The Multichannel mode is not available if you select a paint object containing an image in Black &
White image mode.
