Well you know, one can get pretty hungry out in the darkroom!(posted 8592 days ago)My motivation is simple, keep the toxicity as low as possible. I’m on septic, so I want to use compounds that are produced by a biological or natural (in nature, not a lab were you can produce isomers that are resistant to bio-degradation) process which are then more readily broken down by the bugs in my septic. Yes, I’ll have to do something about that pesky silver laden fixer, but I’m trying to minimize the use of non biological based chemicals.
