I remember something about a photographer who would take three pictures, each with a red, blue, or green filter. Then they'd had tint the images and somehow combine them in to a single color photograph.
that was a russian photographer, who impressed tsar nicolas 2 so much he was officially commissioned to do a tour of the empire and take as many photographs he could. I havent found a complete source for his pics online yet.
these aren't complete and you may already be familiar, but for anyone interested:

yep, in many ways that's the easiest way to do it. co-registering the 3 photos can be tricky, especially for close ups. but it's bulky and laborious. it's not really until the filters got incorporated into multilayered film that it became cheap enough for widespread use.
