I haven't followed too closely this HDRI discussion.
  Looking at the few pages and images posted to p.b.i I see that I haven't
the slightest clue about what is it all about. The images look very nice,
but I can't see what is the HDRI thing in those images.

  So could someone explain exactly what is HDRI and how it affects
rendering? If it's an algorithm to make something better, could someone
make images where the regular way is used and the same scene with HDRI
is used so that they can be compared side by side? If it's something
completely new, not comparable to anything in POV-Ray, could someone
explain how it affects the images?
