    Hi, I shot a roll of neopan, just to evaluate the film, not using all the film up, then I shot a few shots of subjects

    Problem is, I was all out of fixer, so I just mixed up some fixer 24 ( a non hardening paper fixer) from scratch and used it.

    Now my negs aren't hardened. No big deal right? It's just an evaluation roll?

    Of course, I ended up getting a rather good shot, on this eval. roll, non-hardened.

    I'd like to keep this negative, but of course, it won't last without hardening.

    What to do, what to do?

    I've been thinking of just soaking in water to get the emulsion soft again then using a hardener, but what to use?

    Most modern films don't need a fixer with hardner. I wouldn't worry about it.

    I don't understand why you think the negative will be lost without a hardner fixer.

    I concur, you should not need it. As long as you fixed for the proper time, at least 5 mins in this solution you should be fine. The negatives may be a bit softer without.

    Ah, I figured it was sodium based. I love my TF4...non-hardening and rapid fix. 3-4 minutes for film...60 sec for paper.

    Got it. Took me forever. No thanks to you clowns! (just kidding:lol:). Seriously though, I had to hit the good old ink and paper reference manuals.

    Kodak F-5a Hardener.

    Water 52deg c-500mls
    fodium sulfite 75 grams
    acetic acid 28% 235mls
    Boric acid crystals 37.5 grams
    Potassium alum, dodecahydrate 75grams
    Water to make 1 liter.

    Mix 250mls of stock sol'n into 1Liter of water (not "to make"), or fixer to make hardening fixer.

    Warning, boric acid powder, dissolves very slowly with great difficulty, prefer boric acid crystals.

    Harden film or paper 1 minute before fixing, or after rinsing. If dry, pre-wet for 3 minutes with distilled water.

    Ironically, I also found de-hardener.
    750mls water
    30 grams sodium carbonate, monohydrate
    water to make 1l

    To use soak the print up to 10 minutes in sol'n, agitating ocassionally.

    Handle prints carefully, as the emulsion is soft and no longer protected by the hardener (DUH!)
