color development - some newbie questions

Discussion in 'Darkroom Developing and Printing' started by Serge Korolev, Sep 14, 2003.

  1. Hello,

    Some weeks ago I've started developing C41/E6 films at home using a small
    Jobo processor. Although the process' results look more than acceptable,
    being a bit of paranoid type, I merely wanted to express some of my
    worries to the more experienced community members.

    So far I've been buying chemicals in the quantities which wouldn't bother me
    much with a storage issue. At the beginning I bought a couple of Agfa
    process 77 half-liter packs for E6 process and a set of Tetenal Monotabs to
    process C41 films.

    1) Tetenal Monotabs are coming in the tablets divided into three plastic
    cans (one for developer and two for bleach-fix) and a pouch of stabilizer
    tablets. Since a few days ago I'd been running out of the originally bought
    set, I reordered two packs and got them with a stabilizer tablets being
    crashed into the pieces. As far as I don't know how critical its
    concentration should be, I am affraid to make approximations at deluting it
    to prepare the final bath. Could somebody consult me on the matter?

    2) Relatively to the latter, it's not recommended to apply stabilizer while
    a film is still loaded into a tank and the last step of the process should
    be completed out of the reels. What confuses me is the procedure of washing
    film out in a tray. I just cannot get it clearly what actually I do suppose
    to do - rinse each part of the film drawing it from one end to another, or
    should I dip it completely into the solution and try to avoid film sides
    sticking together?

    Thanks,

    Serge

    Stabilizer concentration is not critical. Divide the crushed bits into the
    original number of tablets and you should be fine.
    The stabilizer can leave gunk on the reels, that's why it's recommended you
    remove the film from the reels. The wet film will not stick to itself. I use
    a plastic dish about 3" high by 5x5". I put the mixed stabilizer in it and
    bring it to processing temp in a water bath. Then I take each roll off the
    reel, by opening the reel, and drop it, still rolled in a spiral, into the
    dish. After the 1 minute soak, I pull it out by one end and hang it.

    The reason for not using the stabilizer on the reels is that it is impossible to
    completely get off. What I did was get a disposible platic bowl that was tall enough
    to submerge a 35mm roll and I use that. I hold the reels with one side down and split
    the reels and then flip the reel over dumping the film into the stabilizer.
    I have noticed a film on the container that I can't wash off!!
