A classic example of confusing the additive properties of colored light
with the subtractive properties of pigment.  After all, if printers need
all three colors to get a spectrum, how are you guys doing it with just
two?

Tell you what.  I'll give a hundred dollars to the first person to show
this works, as described.  Two regular filters making full color.  (By the
way, this is not a winner: http://www.creative.net/~wc/dandy.htm )

If you find out your photos are made up of only two colors, then we can lay
this voodoo emanon optics aside and talk about something interesting.

Your pal, Tom
