I finally got around to developing a roll of film from my old Agfa medium format camera. The lens is flipped in this one and that is what is producing the distorted edge effects. I keep meaning to flip it back the normal way and see how sharp the lens actually is, but I do like this effect.
These images were taken on a roll of Arista EDU 400 film and developed in Rodinal 1:25. I've yet to do any side-by-side comparisons with Tri-X, but the Arista EDU film seems pretty decent and is usually a couple bucks a roll cheaper.
