I've just about finished with refinements on my DIY "lightweight" 11x14 camera...and still have twenty four sheets of Tri-X in that format, with the expiration date being June of....1988!
I'd last used this film with good success about two years ago, with my "go to" exposure and development regimen for outdated films...setting ISO at around 80 and using a strong dilution of 72 F HC-110 for a bit of extra time to boot.
But as the HC-110 is now gone, I'll be testing a sheet with Pyrocat-HD...and my gut says to use it double strength (2/2/100) and for a generous amount of time (20 minutes), and perhaps up the agitation a bit - starting with one minute of tray rocking, then rock every thirty seconds for the remainder of development.
At any rate...if anyone here has used Pyrocat (in trays) for processing "seriously" outdated films, I'd love to hear about it!
Note: While I'm tending towards PMK for sheet films these days, I'm thinking that Pyrocat might be a better choice for films that are "seriously" outdated. Again...comments welcomed!
