<p>You can change an image from its original mode (source mode)
to a different mode (target mode). When you choose a different color
mode for an image, you permanently change the color values in the
image. For example, when you convert an RGB image to CMYK mode,
RGB color values outside the CMYK gamut (defined by the CMYK working
space setting in the Color Settings dialog box) are adjusted to
fall within gamut. As a result, some image data may be lost and
can’t be recovered if you convert the image from CMYK back to RGB.</p>
