Nice! I had the opposite experience this week-- a box of very old 4x5 Panatomic X was, finally, too damn old (the date had broken off the box, but the old-style labeling probably indicated 1957 or so). It was an open box when I got it, so my rule of thumb of "Pan X in a sealed box from 1963 or newer is plenty usable" is stretched but not broken.
Just processed a roll of 35mm Tri-X from around 1990s. Used semstand Pyrocat-HD 1.5:1:200 for an hour with an initial agitation of 2min and a midpoint agitation for 15sec. Negs are just fine, with no particularly noteworthy fog.
I would have thought that with the films I developed that the faster films like TRI-X and TMY2 would have shown a little more fog than the slower films, but they didn't. I might try semi-stand Pyrocat-HDC with the outdated films I have. I've not really tried semi-stand with Pyrocat and this might be a good time to try it. What is your agitation regime with your Pyrocat-HD?
Pyrocat-HD 1.5:1:200
Prewet for 3 min
2min initial agitation
15sec at 31min
Pull at 60 min
More here. See especially the Updates section at the end:
Thanks, after Christmas, I'm going to give that a try and see what I get.
Read my notes in the document above first. How you suspend the film is critical.
Yes, I'll follow it to the letter.
Please do share your results.
Note that I do everything in Pyrocat-HD with Part A in glycol, not -HDC. I've no idea if this has any bearing on propensity toward bromide drag and streaking. It will be interesting to hear your outcomes.
In my books your catch is fairly modern! I've been using (slowly!) a bunch of 23 boxes of glass plates from 1940's and even earlier. Some of the stuff only has very slight silver mirroring on the edges. All of the Ilford plates have been good, haven't tried Kodak yet. Sensitivity is much reduced, like from 200ASA to 25. I've had good results with powerful developers like Ilford ID-33, (may even try some day paper developer, if lazy). Some more in Flickr: glass platesView attachment 357742
