For the first time, I tray processed my four sheets of 8X10 film. Exposures made with my DIY pinhole camera of some Tri-X 320 that was is a couple of holders I bought 2 or 3 years ago. No idea how old it was. Processed in D-76 that I would estimate was 10-15 years old. three of the four negatives were OK (printable) and the forth is questionable. That having to do with exposure rather than materials. I will get them printed either tonight or Monday and post them in the gallery. Bill Barber
