color on 24 bit images does result in artifacts, one can up the bit depth
for those resolutions to avoid the math problems, but still it's a

think of the problems in cameras.

How long until the selection of lenses for digital cameras matches that of
SLRs?   For this to happen, digital will have to get to good enough that
the format can be frozen long enough for multiple lens types to be
developed. A 28-200 zoom, but at what quality level? Remember a lens used
for digital work _must_ filter out all detail at less than half the
sampling frequency to avoid aliasing.
