I may be way off with this and I don't mean to hijack this thread but would it be possible to print color from black and white buy using color paper and placing a couple of different filters in front of the film (cyan yellow etc.) and making a couple of exposures on the paper?
That's what we are talking about doing. But you will need three black & white negatives. Each negative will need to be exposed through a different filter: one through red, one through green, and one through blue. Then each negative will need to be printed onto one sheet of RA4 paper in sequence, and it will need to be exposed through the same filter it was exposed through on the camera. My questions are regarding how to get the three negatives to line up to keep the image in sharp registration since each one will need to be placed in the enlarger one at a time.
