Alright guys, here's the deal. I've been plagued by a strange yellow-brown stain on my prints, and I have no idea whats causing it. It looks like some sort of fixer stain, but I'm almost certain that it isn't, and here's why: 1. The developer is Michael Smith's Amidol for Azo/Lodima. It turns everything yellow, but that washes off in a few minutes of running water, so I'm not thinking thats the problem. 2. Stop is standard acetic acid, 50cc 28% in 1L water. No issues there. 3. Fix is Kodak rapid fix without hardener. Prints fix for 5 minutes, and it wasn't exhausted, so we're good there. After that, I put prints in a holding tray with plenty of water, and the yellow from the amidol leeches out and the prints look great. Nice whites, fantastic blacks, the whole deal. Now here's where it gets funky. I put all the prints in a new tray with new water, and everything's still good. Then, I pour 25ml of rapid selenium toner into 64oz. of water, which I realized later was quite cold. Still, shouldn't be any problem, right? So I put a test print in to see how it will look, and it looks ok. I've never used Lodima before, so when it goes completely warmtone after Michael's recommended 3 min. in toner, I think 'ok, thats what it does.' So then all the prints go in, and they all do the same thing: blacks go a little warm, but everything else goes a light yellow-brown. And the finale: once the prints were in the wash, the yellow-brown 'warmtone' effect began to dissipate, but not evenly, and not from all the prints. So now some are completely yellow, some are completely white, and some are splotchy. After I realized it was a stain, I ran out and got some HCA (I didn't use any initially because I was out. Could this be the problem?) and hit them with that, then washed again for an hour. No change. Any thoughts? All help is greatly appreciated, because before that stain, the prints looked great. I'm pretty sure I can't get rid of it, but it'd be nice to know what went wrong so I can avoid it next time.
