------------------------------------

That particular shot was from a Lumicon hypered roll.  I'd be very
interested in seeing the comparison to the non-hypered case but only if
you're going to do it anyway, since the SG800+ emulsion is ont
indefinitely available anymore.  Some say that it's not worth hypering
the SG 800+ emulsion but, OTOH, I'm very often working at f/10 and have
noticed a visible difference in density on the negative in a number of
subjects, most notably with an enhanced blue and green response.  M27
should provide a good test case.
