Even as ray tracing is a pretty snappy algorithm and POV-Ray does it very
well indeed, it seems to me (from my own experience and the works of
others) that the best results often are obtained with a little bit of
'un-physical' modelling.  There are so many approximations that have do be
done that this is not really surprising either.  For example, see this post
for a convincing example:

In my rad room I stil have recursion_limit > 5 (I plan to decrease though)
with brightness in the 2+ range.  Unphysical?  Could be, but I get the
pictures I want.
