THIS is what I'd like to at least get working myself--I'm particularly interested in two color that can be merged (mirror images)--I'd LIKE to register 2 pieces of regular film (reversal processed) in glass to make a 2 color transparency.
now what would be the quickest way to do this, you experienced people? Say I shoot 2 sheets with 2 different filters (one with reversing prism or mirror) for starters. Now does anybody know of something right off the bat that can be used to dye/color the 2 color records--I've seen the edwal toners--I'm thinking these color the darker portions of the transparencies rather than the highlights--but is that what we want then? If so, I'm thinking I'll buy me some green and red toner and have at it. If I need the clear portions dyed, then would not 2 roscoe filters work sandwiched outside the transparencies?--I get the feeling that you need separate white light sources for each though, right? So that can't possibly work--but that "kodachrome" seemed to work, so I'm thinking there was some kind of a registered screen in there then so you can use the same white light source (light table).
