Well, Azo is a developing out paper (needs developer to form the image). Something like Centennial (POP) would probably work for printing, maybe even making a paper neg., but, talk about being slow, for a neg. Regular photo paper is slow enough in a pinhole. I think you can get Centennial in RC as well, though I'm not 100% positive on this. RC paper is pretty durable and easy to use in a pinhole. I agree with the others though about keeping it as simple as possible.(posted 8598 days ago)
