    Hypam has an undiluted pH of 5.5 or so - it very mildly acidic. It is pretty low in smell, and it is relatively inexpensive.

    Rapid non-acidic fixers are just fine with pyro-stained films. I've tested pyro with acidic (pH 4.5) stop bath vs. a water bath, and I found no significant difference. Rapid fixer will not make any siginificant difference as well.

    Eastern European films, based on older emulsion formulae are not.
    What about Foma 400 and Agfa APX100? Would I need a hardening fixer for those?

    Foma 400 might need hardener, I haven't used it and I can't say for sure. APX100 doesn't need hardener. It was quality film from a big western european manufacturer. But Agfa is kaput since 2005...

    EDIT: See this thread about Foma films & hardener.

    Yes, they smell...but it is a good smell.

    Something that's been alluded to in one or two previous posts but ignored by many others is the fact that there are several common fixer odors:

    • Fixers based on ammonium thiosulfate might smell of ammonia -- or they might not. In my experience, TF-3 has the strongest ammonia odor, TF-4 has a reduced but still distinctive ammonia odor, and Kodak Flexicolor fixer has the faintest hint of an ammonia odor.
    • Hardeners seem to have a distinctive odor -- or perhaps that's the smell of the acids used to make fixers hardener-compatible. (I'm not sure which is the case -- or maybe there are two different odors.) This is definitely true of Kodak's standard hardening sodium thiosulfate fixer.
    • Although not an odor per se, fixers can produce gases when used, and these can irritate nasal passages. I found this was a problem with Kodak's standard fixer, and was the reason I stopped using it. I always felt like I had a mild sore throat for a day or so after a darkroom session (especially printing sessions). I believe this effect is most pronounced with acid fixers.


    Depending on what one finds objectionable, the best solution for one person could be the worst solution for another. For instance, I'm not all that bothered by the ammonia odor, so I now use TF-3 for most B&W fixing. It lacks the nasal irritation problem that I find so objectionable, and TF-3 works fast.

    Since BetterSense specifically mentioned the ammonia odor in his original post, I'm guessing he'd find TF-3, and perhaps even TF-4, unacceptable. Of the fixers I've used, I'd therefore recommend he try Kodak Flexicolor fixer. (Presumably other C-41 fixers would have similar odors.) This is the rapid fixer with the least ammonium odor I've used. Note that Flexicolor fixer, although marketed for color film, works fine with B&W film and paper.

    Kodak's Flexicolor fixer (see it here) has almost no odor, and works like a champ. It is far less smelly than Kodak's powdered sodium thiosulfate fixer. I know it is designed for the C-41 color process, but it is nothing more exotic than a standard, and well buffered, ammonium thiosulfate rapid fixer. There is no hardener and it is almost neutral ph. Best of all, it's cheaper than dirt and has fantastic capacity. I dilute it 1+9 for B&W films and prints, and have absolutely no complaints.

    Wow, that IS really cheap. I wish freestyle carried it. I might have to transfer the contents of my freestyle cart over to Adorama and do some calculat'n.

    edit: Adorama doesn't have arista premium. doh.

    I love the smell of hypo in the morning.
    D-76 is a standard developer, although not one I use.

    Although Freestyle doesn't carry Kodak Flexicolor fixer, they do carry Silver Pixel C-41 fixer. Unfortunately, the only quantity is "2x10 liter," so that might not be a good option if you're a light user.

    Isn't that the smell of victory?
