I quote from my Canon 350D user manual:

"This is mainly used for commercial printing and other industrial uses. This 
setting is not recommended if you do not know about image processing, AdobeRGB, 
and Design rule for the Camera File System 2.0 (Exif 2.21).
Since the image will look very subdued in an sRGB personal computer environment 
and with printers not compatible with Design rule for Camera File System 2.0 
(Exif 2.21), post-processing of the image with software will be required"
