How do you process your sheet film? In school we used stainless steel tanks that held a gallon of chemistry IIRC. We ran replenished D-76. Now that I have a 4x5 camera, obviously how I'll process the film has crossed my mind. I'm inclined to get deep tanks since I'm used to that method, but I was wondering what others use. Obviously that requires a darkroom, which I have access to at the local art gallery. I have emailed the darkroom manager to ask if they have any 4x5 processing equipment, but I'm thinking the answer is no. The stainless deep tanks are expensive and I can't even find the hangers. I've heard of the Taco method of processing 4x5 film in a Patterson tank, but I don't own a Patterson tank (my professor in photo 1 said plastic tanks are not compatible with professional darkroom procedures so I gave it away). Not really interested in buying another one either; I have 1, 2, and 4 roll stainless tanks (Nikor style with 35mm and 120 reels). I've seen daylight tanks, the Combi Plan and Yankee. Are they any better or worse than deep-tank dip and dunk? How about tray processing; that seems to be a good option as well. I feel sure the communal darkroom has 5x7 trays. Any preferred methods? Anything I should steer clear of?
