    Hypo with C-41

    What (if any) problems would there be if I used regular hypo to fix C-41 film?

    I have made a separate bleach bath, hence my need for a fixer.

    Plain Hypo may not be aggressive enough to do the fixing stage. Try it on a short strip of unexposed colour neg film and see how long it takes, bleach first of course for the normal time.

    If it is simply an issue of not being aggressive enough, I am fine with that. I develop via drum and can wait all day while I am doing something else.

    It means that some Silver salts can remain behind and these can stain your film!

    The issue that I have is the only c-41 devs available to me are in powder form (Canada) which means I have to suffer with blix. With last batch I developed, it took me a few months before I had a chance to look at them. Too late, the blue-bleach-bypass set in. Without the ability to get CD-4 shipped to me, I am stuck with them. What I can do is mix my own bleach and use a separate fix.

    What I have is 5 lbs of hypo. What I use is ....

    Water (125°F/52°C) 500 ml
    Sodium thiosulfate 250 g*
    Sodium sulfite (anhy) 10 g
    Sodium metabisulfite 25 g**
    Cold water to make 1000 ml

    Which also fixes tmax quite well.

    I don't have the stuff for a traditional C-41 fix now, but that can be easily obtained. I was more concerned about side effects that I was not aware of.
