It's an interesting film. It works well with Rodinal. I don't like the blooming that happens to the speculars because of the lack of the anti-halation coating. I bought a 300 ft roll and half of it fits in a Watson loader because the film is so thin. Someone on the Internet who claims knowledge of the film says it was designed for traffic cameras. I have no idea if he know what he's talking about but it's certainly a plausible notion. If someone wants 150 feet of it DM me and we'll work something out.
