I bought this can of Kodak 35mm cine version of Tri-X film from late 50s in a hope to find it exposed, but it turned down to be not. So I used the opportunity to check my old film development process on it. First, I put it in my FED-2 rangefinder camera and exposed at 50 E.I. (originally it was 320 ASA but 50 ASA is my best guess of what's left of it), I also bracketed with +1 and +2. Then, I used my standard process for developing fresh Tri-X (4.5 min @ 75F/24C in TMax 1:4) and it turned out to be heavily fogged, barely ptintable/scannable. Then I developed it in 10% HC-110 at 50F/10C for 2.5 minutes (the time had been calculated based on test). It came out ok. Here is how it looked after the development:
The top 2 strips are standard development, the bottom 2 are my old film process.
I thought about using the film. Then I thought better of it. It is old, it has fungus in emulsion.
It could infect my other films and cameras.
