Yes, well said, Toby. Consider what looks like a problem of
lesser magnitude, for machines to make pictures bigger and be of
equally good quality when you don't have the rich informational
base of a negative. It is well known to be quite hard to enlarge
a digital pic well beyond it's natural size through simple
algorithms. Reducing them in size is quite a different problem
and quite tractable.
