I've been doing some of my own developing now for several months, using rodinal. It's pretty dependable, seems like I can't really screw it up. Til now, the only minor issue I've had was getting the fix level a little low, so I had some edge effects, but they were no big deal. But I developed a roll last night, and the scans are all messed up.....very posterized. I'm hoping someone has seen something like this and can tell me what the problem is. I guess it's possible it's the scanner, but I suspect the developing process somehow. It was Rodinal 1:25, for 10 minutes, with agitation for 5 seconds every minute. I've done this many times, and never seen anything like it. Same bottle of Rodinal, always. The film is LegacyPro 100, and is from a 12-pack out of which I've used 7 or 8 rolls already, with no issues. This was done just the same as the last few times I've done this, except for a couple of differences I would have assumed to be minor: 1. The tank and reel. I've been using a cheapo plastic setup, but I got a Kindermann stainless steel tank with two reels on eBay this week, and used those. The tank and reels arrived clean, but were obviously not new. I washed them thoroughly in soap and hot water, then rinsed them thoroughly before use. Any possibility the new tank could have anything to do with this? 2. Possibly old fix? I'm using Clayton RF19 Rapid Fix. The stuff I used as been recycled for at least 4 or 5 rolls, and this recycled dilution has been stored for 2 months or more. I don't time my fix, but rather I just fix a scrap of film concurrently in a small dish, then let the roll in the tank fix for a minute or two longer after that's done. This time I noticed the fix seemed to take longer.....maybe 3 minutes or more for the scrap. But it did ultimately clear, so I wasn't too worried about it. I've included a sample from this roll, along with a close crop. Anyone seen a similar effect before, or have ideas?
