    How was the consistency? I guess developing other photographers films makes consistency harder to judge unless you run process control films.

    Another related question: How did you hang the sheet film to dry?

    I ran process control strips, it was pretty consistent the film was put in a Marrutt drying cabinet:

    Film is dried in the hanger used during development.

    is actually a very similar developer so should also
    work at that dilution. For starters I'd give a 120 roll
    in 500ml of solution 20 minutes with 2 or 3 inversions
    every other minute.

    Yield, 16 rolls per liter of stock strength. Dan

    You can not stretch it by dilution because you need a minimum 4 oz of stock to make any dilution for 80 sq in. of film, or 1 36 exp roll.

    to use 1:3, mix 4 oz stock and 12 water . A 16 oz tank is therefore required for a single 36 exposure roll .

    Has that 4 oz minimum been verified by testing?
    At one time D-76 was suggested to be used only
    full strength . Then Kodak OK'ed 1:1 one-shot.
    Now users report 1:3 one-shot is OK.

    I've never seen, other than by myself, D-23
    recommended any more dilute than 1:3. After
    a few rolls of 120 through at 1:7 I can say it
    works very well.

    I don't use D-76 but if I did I'd test to find it's
    minimum. Without some independent verification
    that 1:3 suggested maximum dilution may as well
    have come off a box of Kodak's D-76. Likely full or
    1:1 strengths are still the only suggested strengths.
    With enough time I think D-76 1:7 can do it. Dan

    Kodak have recommended using D76 FS + replenishment, or alternately 1+1 or 1+3 for as long as I've been active in photography, late 1960's.

    The issue with over diluting a developer is you run a high risk of compressing the tones as you will exhaust the developer, in some cases this might be beneficial, and people do this deliberately with Rodinal at 1+100 or 1+200 where a scene contains a long dynamic range/high contrast. But for normal lighting or the typically flat lighting found in the UK the last thing you want is to flatten & compress the tonal range.

    Although Ilford and Kodak don't publish a time a 1+2 dilution is far better in my experience than 1+3 with ID-11/D76.
