I'm thinking about loading some film holders with photo paper rather than film. Does anybody know approximately what the ISO would be for Ilford Multigrade when exposed in camera? thanks ---jb.
A good starting point seems to be ISO 6 (at least, that's what I've read and seen on YouTube; I've never shot paper negatives). You might, however, find a yellow filter helps tame the contrast, and you'll then need a 2x filter factor, at least (and may need to experiment a bit to find the sweet spot, as well as composing with the concept that the film, so filtered, really sees only green).
