Image Enhancing filters

[P3D Dr. George A. Themelis <fj834@xxxxxxxxxxxxxxxxxxxxx>]

One of the interesting items that I bought in Detroit last night is a pair
of "Image Enhancing" filters for the Realist.  These do some selective
filtration and change colors depending on the color of light.  I have a
filter for my SLR that I have never used.  In tungsten light they appear
pinkish.  In fluorescent light they change to white, greenish.  The fellow
who made the Realist filters just cuts smaller sections out of a larger
filter puts it over a Realist filter holder (the small ones that go over
the lenses).

I plan to use the filters and see what they do, but I would like to hear if
anyone has any ideas or comments on the use of these filters.  Why and how
do they work?
