I use my Polaroid Model 800 with paper negatives, and it does real well. I can't recall right now the shutter settings, but I've metered the scene with a handheld and referenced the various speed and aperture combinations of the 800 from its manual to find the right setting. With a 4x5 film box loaded with sheets of paper, you can reload the 800 out in the field using a changing bag. Loads of fun, and keeps the camera in original condition.
