• p. 165, Indexed Colour

• p. 183, Channels

  This image is in RGB colour, which makes the channels separate cleanly as shown in Figure 5.23, because of the distinct red and green areas in the photograph. Try converting to other colour modes and looking at the individual channels (use the Channels panel in Photoshop). Lab is interesting.
