1) I can process 2 sheets of 5x12 film in a 3 inch x 12inch cylinder tank (Nikkor 5 roll tank) using the taco method. I altered my dilution for Pyrocat-M to 22mlA + 18mlB +1800mlWater basically adding 45% over my normal 15mlA/15B for a single sheet as an educated guess. Processed my normal time of 13 minutes at 70*. Both images are normal looking.
2) When you accidentally load two sheets in the holder and don't know it until you unload the top sheet, you can leave that second sheet in the holder and expose it another day. For FP4+, the anti-halation layer prevented the initial exposure of the second sheet. I was hoping for a cool double exposure when I shot the second sheet by itself but that did not happen. I suppose scene brightness may come into play at some point and allow some light through. The initial shot was fairly early in the morning, and the second shot in brighter conditions. No double exposure evident.
3) TF5 fixer mixed 1:9 working solution is too weak after sitting for 3 months per the clip test. Replenishing 1800ml with 100ml stock was enough to bring it back for todays processing of 4 5x12 sheets. I put a sticker on the bottle to remind me to test before use.
