FP4 too low contrast

Discussion in 'Darkroom Developing and Printing' started by Dick van Nierop, Oct 7, 2003.

  1. I've been using Ilford FP4 for a while now: exposure at 64 ISO,
    development in ID11, 1+1, 20 degrees, 10 minutes (as the suggested 8 min
    always led to too low contrast). Even with this longer development time
    I find that I have to use filter 3.5 or higher exept in really high
    contrast conditions. I plan to develop even longer for normal and low
    contrast conditions (while increasing the film speed to 125 ISO). Say 12
    resp.14 minutes.
    I find this a very strong discrepancy with manufacturer data. Can anyone
    comment on this. Am I doing something terribly wrong or what?

    Thanks,
    Dick van Nierop.

  2. This is not the usual experience with FP4+ as most people struggle to
    control the film and its tendency to go too contrasty..... I know
    there's supposed to be little or no difference, but I always seemed to
    get lower contrast on FP4 with ID-11 vs D76. Not just lower contrast,
    but thinner negatives, in general. I ended up using FG7 with good
    success and have recently been playing with some tanning developer
    stuff and am very happy with that, too. Is it possible that your
    developer is showing some age or oxidation? I've seen comments about
    it not having the shelf life of D76 but couldn't tell you from
    personal experience in that regard. My ISO with FP4+ and D76 1:1 was
    100 with generally the same development as you are using but 70 degree
    F and 10.5 minutes. The FG7 negatives seem to have a nicer glow and
    I've settled into a comfort level with it at the recommended process +
    10% time (my diffusion rig seems to like that better).

  3. What film format? Do you use other films as a check? FP4 is anything
    but flat in my book! Try Acutol on FP4 for an amazing experience.

  4. Is your stock developer fresh? Do you dilute it and use it
    immediately or do you let it stand a while, a long while, before
    using it?

    Using a diffusion or condenser head?

    How are you determining your exposures? In camera light meter or
    handheld? Reflective or incident? Had you meter(s) checked lately?

    What paper developer? Is the stock solution fresh? Are you diluting
    it just before using it?

    What paper? Is it good? I've gotten whole 100 sheet boxes that were
    slightly fogged (Don't know how. Chemical? Heat? X-ray?),
    resulting in very low contrast prints.
