    Purple edges on tmax 400?

    Hi,

    I just developed tmax 400 in ultrafin plus. The negatives look ok, but the edge (perforation) is purple on some places. I've not seen something like this before. What could be the cause?

    lack of fixer. tmax films need longer fixing times . However, it is not unusal for the edges of film to show issues, either with the developer or fixer not getting to those edges bound by the reel.

    Is that remaining emulsion?

    Sometimes when I process film in my stainless steel reels there are spots that don't get fixed out during processing where the film touches the reels.
    I also use TMax 400, in both 120 and 35mm, and even though I fix for seven minutes with lots of agitation, I sometimes still get this effect.

    I have never worried about it, because it doesn't affect either the negative or the print quality.

    Sounds just like you haven't got rid of the purple dye completely?
    Cause could be fixing and HCA/washing wasn't adequate.

    Sounds like a fixing problem. T-max usually needs time in the fix.

    Aha, the reel preventing fixer access to emulsion would explain this. Since it's just on the edges, I think I'm fine.

    I get this VERY often with my tmax400 and stainless steel reels. The shape of those "markings" always match right where reel spiral would be. Then, those "markings" never get into the image areas. Even with 10 minutes fix with Kodak fixer. Like Thomas, I never worry about it.
    Develop, stop, fix.... wait.... where's my film?

    I also almost always see this sort of thing when using SS reels, but seldom or never with plastic reels. If you're using SS reels, jernejk, I wouldn't worry about it. If you're using plastic reels, it could be the same thing is happening because your reels are different from mine or your loading technique is different; or it could be something else, like insufficient fluid volume. (If the tank isn't absolutely level, part of the reel might poke out of the solution, leaving underdeveloped or underfixed bits.)

    I just experienced the same problem with my TMax 400 II. In my case, I had done a fixer exhaustion test before the devleopment. Where my fixer normally fixes the film in 5 minutes, the test said I would need at least 11 minutes to fix the film. In short, my fixer is nearly done. My conclusion: Old fixer is not effective and will not fix the edges of the film that are in contact with the steel reel.
