Is there or isn't there a weird effect when light goes through
plexiglass?  I made a contact print frame once with a new, scratch-free
piece of plexiglass about 1/4 inch thick.  Contact prints made with
it came out *very* bad, with lots of strange things at the edges of
objects in the pictures.  I changed to a regular piece of glass
about the same thickness, and things became normal.  I thought that
maybe there were more internal reflections or something...
