According to Kodak's website and B&H, their Edupe film is still available. 4x5 is fine. I am trying to duplicate MF stereo pairs. 4x5 seems like it would be easier to work with (sheets) vs. a roll for contact printing. I guess I would need an enlarger to do it myself. How much would I expect to pay for a 4x5 color enlarger (assuming I will need color filtration and test runs to get things right for each pack of film). Of course, if Edupe only has a year of life left in it, I wouldn't want to set up this whole system would I?
