Maybe this goes without saying in this newsgroup, but 24 bits of color
value for RGB might be called near photographic quality, as far as color
rendition goes, but 5 bits (32 levels) probably is not very close.

And that's only color rendition.  Even a 400dpi image is not remotely
close to photographic quality in resolution.  I don't have any exact
figures at hand, but I would suspect something like Kodachrome could
do well over 10,000dpi.  Of course, an ISO 1600 film might be only 
600dpi!  :-)
