Virgil,

Thanks for sharing your experiences.  Pretty clever.  I was thinking that
the big klutzy edges of filters would kill the process -- not exactly knife
edges.  Slide film is a brilliant solution, both colors in the same thin
plane.  Too bad they don't make color emulsions on glass anymore.

Wobble Master...now there's a wonderful old brand.  I've owned many of their
products ;^)
