Hi all, I got a pack of 4x5 direct positive from a friend recently and decided to load it up in the 4x5 last night and experiment. I exposed for ISO 4 and it was perfect. It is very contrasty, so I will need to pre-flash next time. I developed in LPD 1:3 for 2 minutes and got supreme blacks. The paper quality is great, easy to handle. One important thing to remember is that it turns all black and the whites develop. This messed with my brain as I put the first one in the developer and thought I overexposed! Whoops. First shot, and hopefully I will experiment more. I plan on building an 11x14 or 16x20 pinhole eventually.
