Taken on Panatomic-X 120 roll film, expired from the 70s. The longevity of this film amazes me. It is very slow, and as such, seems to age well. This was shot at EI 32, which was among the various listed speeds for this film. Various Kodak literature lists the film as ASA 40, ASA 32, or ASA 25, but my guess would be any could be made to work given correct processing. Still, given that evaluation, one must inevitably conclude that it has lost almost no speed over time, and that it remains resistant to fog even now. This was developed in Rodinal 1:50 for 11 minutes. The camera was a Mamiya C330 with 105mm lens.
