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. For example, 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 repre-
sent 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.
