    [QUOTE=Maine-iac]I'm considering a switch from tray development

    If you were not so wedded to one-shot developers I think
    you would consider tank and hanger processing. Dan

    I find the best way to use the Krause/Gepe/HP Combiplan tanks are as-if they were deep tanks but instead of replentishable chemistry, mainly one-shot. Since they are small I find one can get away with 2-tanks. Once the film is in developer its significantly less sensitive to light and while one will tend to work "in the dark" it does not have to be "that dark"--- the same observation applies to the BTZS tubes. Since I driop my film into a filled tank of developer and remove it to an intermediate stop-bath, I have much better control. The lids are just used to cover things up and instead of inversion the film hanger is moved up/down (as with a Nova). While I also have a 2509n reel for my Jobo I don't use it for B&W.

    Been using mine almost a year now and no complaints except the slow fill/drain (which hasn't caused any problems). It's a little hungry for chemistry at 1L but I like running 6 at a time - with E-6 it's all exposed "by the book" anyway. Paid $88 U.S. at Porter

    I suppose one-shot chemistry with tank and hanger
    processing would be practicle. I was thinking of the
    chemical loaded soups used years ago when I used
    the method.

    A liter of FX-1, for example, has a total of 8 1/2
    grams of chemistry. In that volume a few 4 x 5s
    can be hanger developed and each sheet can
    be given it's own specific development. Dan

    Robert White have a box of spare Combi Plan parts. So my new lid is in transit.

    They no longer supply the complete tank system.
