Hi, I've got a Kodak E-6 kit that I purchased over a year ago and began using at that time. I don't shoot a lot of E-6, so I've still got a lot of this kit left. The last couple of rolls I've processed have come out rather dark, and the last one wasn't fixed properly. (I caught a strong whiff of ammonium as I poured out the fixer, and the results were obvious. I used some C-41 fixer to fix again and that seemed to clear the film.) I'm therefore guessing that the first developer and fixer have gone south. So my question is: How much of this kit is salvageable? Can I just buy a couple of items fresh and continue using the rest of the kit? Or is everything in the kit so close to being worthless at this point that I should just write it off and discard it all? Even if most of it's bad, is there anything that's likely to have a particularly long shelf life, that I could keep for use in case I accidentally spill something from the next kit I buy?
