Is there any easily obtainable/mixable recipe for a black and white film fixer. The thing you use after developer. I had no luck with google. There are numerous developers, commercial and mixable from common chemicals, but none even mentions fixers.
I'm asking since mostly i'm using b&w film for fun and experiments, so repeatability and quality are not important. Even more importantly, the only non-professional film shop is ridiculously overpriced and is out of fixer most of the time.
Probably, i could figure out, what nasty stuff i could use by researching the chemical process of film fixing. Still i was hoping there are some well known mixtures i'm not aware of (similar as paRodinal, from developers). Any keywords or links are welcome.
Currently, it seems that my agfa age fix i've run out of, smells a bit like vinegar.
Is it worth trying (the vinegar)?
