Among the trove of expired film I was recently gifted were six rolls of 120 Tri-X Professional with an ISO of 320. I decided to shoot the first roll with a use-by date of 08/1992 in my Welta Perle folder. I made a few shots in my neighborhood and then spent a morning walking around the UNM campus.
I gave the film an extra stop of exposure to compensate for age and then processed it in L110-b for six minutes at 20C. The negative density was a little thin, but there were no obvious age-related artifacts in the images. I'll try an additional stop of exposure in the next roll, and maybe add another minute in the developer as well.
