I want to make some tri-color gumprints using color separation negatives using ortho film:
The idea is starting out with 35mm color negative film. Then, using a slide copier, making three positives with unknown filtration on 35mm B+W film for channel separation. These three positives would be used in the enlarger with ortho film to have enlarged negatives.
Would this workflow feasable ?
thx for any tips, Marc
