    I have had my share of major failures and screw-ups with 12X20 so I know how frustrating this can be. Just for the record, however, I have been using TMY from this order and have not seen any problem with fogging.

    Bear in mind that an ASA 400 film is a lot more likely to show fogging from camera problems than one of ASA 100. A minor bellows or holder problem that might not show up with the Efke could cause major fogging with TMY.

    Jim,
    I have gone through two ten sheet boxes of 12x20 Kodak Tmax 400 film from the JandC order without any problems. Good luck!

    Well, Sandy and Ole were right on. The film is clean. A little more film base plus fog than I would have expected but no artifacts. When you're wrong, you're wrong.

    Jim,

    I was going to ask if the delivery truck drives past the Nevada Test Site on the way to your place ;^)

    Ditto here. I have shot 8x20, 12x20 and 11x14 TMY and have and have had no problems and minimal FB+F. Of course, I am being extremely careful to keep my film holders in covered light tight septums in the field and a dark cloth over the camera back at all times. Hope you figure out where the problem is.

    Cheers!

    Check the bellows for cracks or tears especially where it attaches to the rear standard/frame. You might have a tear or seperation that opens with bellows extension.

    Jim,

    Sorry to hear about your troubles with ULF film fogging. As we go up in sheet size the ammount of troubles seems to multiply.

    You haven't mentioned much about the holders. Are they older? I know you inspected them before loading film, and they appeared light tight, but did you test them with a sheet of paper and walk them outside.

    I have older 8x20 Korona holders that are light tight in the studio but can not be exposed to direct sunlight outdoors without fogging. It seems the dark slide is not fully opaque. I've changed out the dark slides for a new sheet on a couple of the holders but still will only shoot with them outdoors if they will not hit the sunshine.

    How are you storing the exposed film?
    Some of the film boxes are not fully light tight either without keeping the film inside a bag inside the boxes. Illford boxes are this way in the smaller formats.

    There are lots of ways for light to get to a ULF sheet of film and destroy the image.

    Well said George. It can also manifest its ugly head as any combinations of these adverse consequences within the entire process from loading holders and developing negatives back in the darkroom. It takes some serious descipline to isolate each of these variables and eliminate them throughout your ULF system.

    Thanks for the thoughtful words. I have 2 holders. They are newer Hoffman holders from the mid '60's is my best guess. I will have to set the whole system up in bright sun and stick my head in from all directions to try to see where the leaks are. Wondering if contact cementing some black felt cloth on the surfaces at the rear where the film holders contact the body would be counterproductive.

    One thing I'm positive about. Once you leave 11X14 the problems seem to mount by magnitudes and I'm starting to wonder about diminishing returns. 8X10 just seems so easy!
