4x5 paper negative?

[jbrubaker]

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).

BTW, you should also be aware that precut 4x5 print paper won't fit a 4x5 film holder -- it's a millimeter or two too large in both dimensions.

We were using EI 3 for pinholes. Buy 8x10 sheets, and cut it down. Photo paper negatives are unique!

Hi JB
it all depends on the light/ time of day. Sometimes paper can be exposed really slow like 3 or 6, other times as high as 24.
