YO! Problem solved!! From horrible negative to solution...

Discussion in 'Darkroom Developing and Printing' started by stefano bramato, Sep 26, 2004.

  1. Who remember previous post about an horrible negative of mine?

    I have done today four tests, with four different developers, new fix
    and reduced fix time. Like you suggested there is something wrong in
    fix... test test test!! Alone in the dark testing today!! Is a rainy
    day!!

    I really think that the negative was destroyed by two differents factors
    at the same time.

    First of all I was helped by a friend in preparing the fix solution and
    other stuff, bEcause he was a friends who wanted to learn more on
    photography, ok?

    First reason:
    He says to me that he did fix solution slightly more concentrated than
    usual, like I use to do. But alot more concentrated: 1:3 instead
    instead **1+3,5** that is very different with rapid fixers. So I think
    that more acidic environment subtle wounded the emoulsion. Then a
    excessive fixing time: 10' instead of 5'-7,5' as I do when FRESH.
    More fixing time and concentration, this time and with this rolls, not
    did more bleach on highlits, like many books says but makes like burns
    and bubbles on the emulsion.

    Second reason:
    not stable water temperature.
    usually in my lab there is always 24°C. This time i can see that there
    are a couple of °C more high and low. But i beleieve that this cannot
    affect at all the washing but can help in desruption of film.

    Sorry people for using NG as reporting my esperiments, but after this i
    feel more sure of my self (and of course, less of my learning friend....
    :D)

    Today tests results with as usual stock treatments?
    Perfect negatives... and I feel more comfortable with myself!

    Ciao,
    Stefano

    i hope so!
    :D
    yo! You're right!! In these times I feel like stranger. in a digital
    world, as thirty y.o. man I feel quite strange when I say that I
    continue to experiment, to learn, and to test film apparels!!

    OTOH i don't want to let get rust my old rolleis and my contax as well:
    they give me satisfactions!! And the film, the dark chamber, and so
    forth is a missing magic!!

    CiaO!!
    Yes I will do with lot of pleasure!!
    HOping not too much destroying my negatives,,, ehe!;)

    RE: stefano bramato

    Take it easy on that film!! Try unadulterated ammonium
    thiosulfate 60%. Dilute it 1:24 if you use 500ml per roll as
    I do with 120 Pan F+. Or try 16 grams of the sodium anhydrous
    form in the same volume of water. Use the fix one-shot.
    The higher speed film you use may require a little more
    of the concentrate.
    Worst case for film fixer is the entirely unexposed roll or
    sheet of film. Testing will determine that worst case amount.
    Try to be nice to your film. Give it or them a fresh,
    gentle fix. Dan
