    acros100, pyrocathd, 3010

    hi togehter,

    i even started to develop my first b&w 4x5 sheets.
    i use a jobo 3010 with acros 100 and pyrocat hd.
    (rollo pyro is not available in europe; i could not find a distributor yet)

    ...but pyrocat hd with the 3010 should give also good results.

    my procedure ( first time ):

    - pre wash with normal water about 3 minutes( 20,5 degrees)
    (for every step: 3010 is always rotating, every 30 sec i flip the drum)
    - solution A and B with 1:1:100 (pure water) about one minute befor using (500ml)
    - developing 9 min.
    - two washing steps with about 500ml water (about 30 sec. each)
    - fixing with ilford rapid fixer 1:4 (500ml) for 5 min.
    - do the washing 20min.
    - photoflo for 30sec.
    - drying

    i don't want to do complicated film testing because my negatives will be scanned with a v750 and photoshoped (don't think this requires an absolute perfect negative?!)

    - how can i easily check my development procedure if i'm on the right way (i'm not so experienced in interpreting a negative by a loupe)

    - i will use about 80ml for a sheet!
    will my results differ if i develop one sheet with 80ml of pyrocat hd (in this big jobo) from developing 10 sheets with 800ml?
    water and fixer i will use always 500ml.

    can you give me further advice for developing acros100 in pyroHD?

    thx for help,
    best michael

    Michael,

    A few notes for you.

    1. Use 1000ml of working solution in the 3010. Results will be better. 1 sheet or 10 you will want 1000ml.
    2. Do not Photo flow in the 3010. Do it in an alternate container.

    The best thing I can say is just do it. Do it many times and then do it some more. Each time you shoot and run a processing session you will learn a little bit. And the experience and knowledge you want comes from lots of trial and error.

    Good luck!

    You don't need 1L for all steps. Actually, using 500ml for the first half of dev time then 500ml for the second half is what i do since 1000ml is a lot of stress on the jobo motor. Since u aren't using the jobo machine it should b fine. Keep wash and fix at 500ml.
