I've been on the hunt for something I don't even know if exists I figured it was time to ask around. I've done some searches on APUG to see if the topic has already been discussed. Anyhow:
Does such a thing exist? Photographic paper (b/w) that can be exposed on both sides? I don't suppose it does...when I think about, the idea seem ridiculous in many ways. Perhaps someone out there has tried making some themselves?
