Hello people,
Please scrutinise my plan: Take three shots (of the same subject/perspective) with B&W film on a 4x5 camera, one unfiltered, and two with a magenta and yellow filter (changing the shutter to create uniform exposure). Develop and scan each negative. "Subtract" the two filtered negatives from the unfiltered to create a Cyan channel.
Now I have four separate images/colours/layers producing CMYK. Print each CMY layer onto clear acetate (like a not-as-good dye transfer, or technicolor print) and the Key layer onto white paper. Slightly space out the layers, so as you move about the print (not looking at it straight on) you get slight chromatic aberrations. Obviously this will require a lot of trial and error, getting the levels right and all, but I am working with a professional print shop specialising in transparencies, I'm sure they can help me out.
WILL THIS WORK? Do I need the key channel? Will subtracting M & Y from the unfiltered shot create C? I know and love Prokudin-Gorksii's split colour images, designed to project RGB images. But as I'm printing them then I am better off splitting with Cyan, Magenta and Yellow filters?
Before investing in filters, it would be good to know whether I should get RGB (25, 58, 47 in Wratten numbers) or CMY (44A, 32, 12) coloured filters.
THANK YOU! Be kind to me, first post.
