Hello all, I'm thinking of mixing up some pyro PMK film developer (easier than i first thought)in the next few weeks and was wondering about what fixer to use. With pyro developers the film is very sensitive to acid (hence no stop bath, only water). It needs to be a non-hardening fixer and the only non - hardening fixer i can get my hands on is Ilfofix II. The problem is this fixer contains sodium thiosulphate which to me sounds pretty acidic, but might be ok. I'd like to circumnaviagte any potential problems as money is rather tight. Any indications as to what fixer (or any other advice on pyro) would be most helpful. and alas I don't have Gordon Hutchings Pyro book at the minute, unfortunately, and can't get my hands on kodak 24 fixer.... thanks for any guidance or responses, ade.
