By the way, your fixing worries me, 3 minutes with one ag. per minute. You should constantly agitate for at least the minimum time it takes to clear a scrap of leader, and fix for 2-3 times that tested time, with several ags. per additional minute. I really "scrub" the film with the fixer. Look how little space is between the coils of film on the roll - it's a different ballgame than a piece of leader floating in a dish of fix. You can't over-fix (reasonably speaking), but you sure can under-fix.I do use hypo clear on all my non-test rolls (sodium sulfite is cheap, my time ain't), and test every roll for adequate fixing and residual hypo.
Heres the thing, i have compared my scans with those of the lab and the difference is significant so its not so much scanner related. Except for the fact that my negs look more contrasty with Rodinal, my negs have pretty much all had the same "look", even with DDX so its not so much the scan, its me

sorry i mean scanned negatives. the negatives from the lab simply look better (overall greytones, grain and sharpness) than mineI'm curious, how do come to that conclusion? If your scans differ significantly to the lab scans, doesn't a scanning issue appear more likely than not?

On a side note ... have you seen this image? A wonderful combination of Tri-X, Rodinal (called Adonal due to trademark issues) and grain.
Looks like ca-ca.
hey, i am not sure what you mean. what is the minimum time you speak of? more agitation meaning the fix spreads better over the negative? as for the dilution of the fix, is it ok?
When you start setting up to develop your film, you likely have fix that's been mixed per instructions (like Ilford Rapid, 1 part fix to 4 parts water). If you've already developed a few rolls or that mixture has been bottled up for a few days, you need to do a test.
You snip a piece of undeveloped film (usually a scrap of leader, just like a quarter inch or so) and pour the fix in (optimally) a clear or translucent graduate or pitcher - I just use a clear plastic measuring cup. Drop the scrap of leader in, dunk it under so it sinks, and start a timer. At some point, the scrap will turn translucent/clear - the matte emulsion will dissolve (thus the transparent dish - you can set it on a counter and tell when it's cleared easier than a dark container).
Fresh rapid fix will take about 30 seconds to clear that scrap of film, and the rule of thumb is double that fixing time. As the fixer gets more exhausted, it will take longer. When mine gets to 60+ seconds, I dump it. And you should agitate the tank for at least double the fixing time you came up with (test cleared in :30, agitate for :60). I agitate pretty strongly, too, really swirl and shake the tank. Then I might let it sit another minute while I prepare hypo clear or something, and give it a shake every 15 secs. or so.
You can't over-fix modern films (unless you get into actual days in the tank). So an extra minute or two is just really good insurance - there's always something to keep you busy, rinsing graduates or getting your film drying space ready.
I test every roll, too. After washing, I blot off some of the clear leader or tail with a paper towel or kim wipe. Put one tiny droplet of straight selenium toner on the emulsion side. If the spot yellows or is visible at all, you need to fix more. (Selenium is handy for negs even if you don't print - you can amp up the highs in a flat negative by a half-stop or so by soaking the neg and then rocking it in straight selenium. Or dilute selenium for less intensity).
I also test for washing, since I use hypo clear on my film I tend to try to wash less. There's a product called "residual hypo test", one drop on the same clear leader from the selenium test, time for 2 minutes, if it yellows, wash more! One bottle will last you ages.
Many folks tell me I'm being too anal - hypo clear and then testing? For film? But I just developed 7 rolls from a desert trip, and the time my wife sat in the car thinking "I thought this was a vacation, dude??", stepping over mummified dogs in an abandoned factory, the hours and hours I spent on Google earth looking for cool stuff on our route and making maps keyed to those spots... and the projects I shoot with models and props and stylists ($$$! Time!!!) - to me an extra 4 minutes or so per roll is 100% worth it.
thanks for all of the info, i acutally brew up fresh chemicals every time i develop in hopes of getting the best results
