I've been a printer and I've been a photographer, I've seen fire and I've
seen rain, in fact I thought I'd seen just about everything until I saw
an elephant fly.  So I'm confused most of the time, but back before
cheese was invented and I was still high school I did a science project
based on some Edwin Land articles.  I  produced very nice color pictures
from black and white transparancies shot through red and green filters.
Two pictures, two filters, project the transparancies through their
respective filters and, hey presto, full color.  There was a ttrick to
it, but there were only two b\w filtered slides.

Of course the rules of color theory may have changed since then, many
things have, look at White Castle hamburgers, they were only twelve cents
when I did my science project.  You could buy 100 of them for 12 bucks. 
Now Tom's $100 will only buy me 243 burgers.
I'm off to lunch,
