I've read on other forums about PN's and thought I would try it. I shot just one yesterday, due to time constraints. I metered for an ISO of 3. The image came out or looked to come out, close, but still would need tweaking for the next sheet. My question is, now that you have a PN, how do you separate it from the backing to use it as a negative for printing purposes? Did I mention that this stuff is FUN!
