Old HP5 Plus and T Max 400. Advise need

[norm123]

Hi
I received a part of old (like new) photographic stuff (Minolta X 700 by the way), filters, a small flash....and 2 films outdated from 1992, HP5 and T Max 400. I am used to process my films at home. I want to know what are your advise about to expose and process these olds films. Usualy, I exposed my HP5 Plus at 250 ISO and develop it with D-76 (home brew) 1+1 and I'm happy with the results. I didn't use T Max since a very long time. So, what do you suggest me? Should I use another dev? Exposure?

Regards

Oh dear, that is old. Prepare for astronomic levels of fog and greatly reduced speed. I'd try shooting a roll at 100 and see if you get anything usable. D76 should be fine.

I have APX-100 and Delta-100 in 30 m, expiration date 2010 year. It was in freezer since 2009 and several days ago I retested both and shows no change in speed, fog+base, and developing time. All like new.

I just finished shooting a bunch of late 1980s vintage T-Max 100. I got good results if I gave it an extra stop of exposure.
Here is a link to the Kodak data sheet for older emulsions that came out in the early 2000s when what was most likely your version of the film was replaced by more modern versions: https://125px.com/docs/film/kodak/f32-TMAX.pdf
HC-110 dil B is often a good choice for older, foggy films. Just remember that there is a bit of speed reduction with HC-110, and a definite speed reduction with older film.

A couple of years ago I had a 1995 vintage 200 foot roll of HP5+

Shot it at box speed, added 1 minute to development times with ID11 stock and every single roll came out fine.

I like the idea of shooting at 320 to be on the safe side, but in my experience HP5+ ages very well.

YMMV. I've had HP5+ expired some 10 years producing reasonable results around EI 200 but certainly not more, and with heavy fog. Early 1990s 400 speed film? Sounds like a challenge.

6 months ago I got a bunch of free 120 film, kept at room temp. I’ve shot a dozen or so rolls. The oldest I shot was some verichrome pan expiring in 1986. Over exposed by a stop it came out ok, but with a noticeable fog. A roll of TMAX100 that expired in 2004 sot at 100, didn’t look at all different than the fresh TMAX100 I’ve shot. I have a few rolls of 2004 TMAX400 that I haven’t shot yet, but that is a different film (TMY) than current TMAX400 (2-TMY) so I don’t expect it to match current nearly as much.

1992? Practically new. Even if badly stored, you should not have lost more than a stop of speed. Grain is likely to have increased and fog as well, but the film should still be well usable. 10 days ago, I developed some FP4 expired in 1982, stored at room temperature, shot at an EI of 50 - the results was very grainy but the fog levels were not much increased. I developed in Rodinol 1+100, stand developed for one hour. Here is an example of that film:

I haven't bought TMY 4x5 sheet film since 2001. I paid 20 bucks a piece for 2 100 sheet boxes, outdated in 1999. Has always been in a fridge, works perfect. As long as it's not been baked probably get something.
I wouldn't use it for your daughter's wedding.

That's good stuff, back when film HAD grain. This modern film blows my mind. I remember Tri-X pushed to 800, grain the size of..... Well, grain, Barley seems about right.
