In the old, analog, pre-television world of printing this is called "in-camera separations." Take three black and white shots using a red filter, green filter and blue filter, and use those for the cyan printing plate, the magenta plate, and the yellow plate, respectively. The black plate is usually made by combining all three negatives when burning the plate.

Ahh, you remember Digi-view!
I had fun moving the camera or
subject while scanning with the different filters.

Folks, this is the basis of: Technicolor.

Nice to see the kids kickin' it old school....

Sounds so familiar..... wait, i remember doing this with my b&w camera with digi-view on my Amiga back in the 80's.
It had a color wheel mounted in from of the lense. It rotated automatically after each shot and combined the images into one color pictures.

New take on an old hack. Sergei Mikhailovich Prokudin-Gorskii, in 1920, did the same thing with glass plates and filters. Of course, glass plate emulsions were *slow*, and you ended up with some fascinating effects. http://www.loc.gov/exhibits/empire/ has his work.

I used a digital camera and Photoshop to emulate the process. I didn't have a set of RGB filters, so I took three normal color photos sequentially, and extract one color from each, and then stacked them. I wasn't interested in reproducing color (since the digicam already did that) but in reproducing the fringe effects. See http://walden.mo.net/~eriko/photo/photo3.htm for what I got. It's something I've filed in the "play with more later" file.
