    It's most likely to be frilling of the edges of the emulsion. Tiny particles of emulsion coming off the edges of the film, any undue temperature variations between Dev, Stop, fix, wash etc will exacerbate this. EFKE films aren't particularly well hardened so a re prone to theses problems. You can use a pre-hardening bath before developing, some are listed in the Darkroom Cookbook, (the 3rd Edition is out very soon).

    Using a tanning developer like Pyrocat, or PMK will help too as the Pyrocatechin or Pyrogallol tans & hardens the emulsion. If you've processed EFKE films its worth filtering and solutions you're going to re-use.

    With good tight processing controls particularly with solution & washing temperature you shouldn't get a problem.

    I quit using Efke film for just this reason. I had the same problems as you have plus some gigantic hunks of crud that always seemed to pop up on my best negs. I was using 35mm. I went through 10 rolls and not a good one in the lot.

    Never again,

    I was within 1 degree on everything last night, the film is still hanging in the rack, I will take a close look at it to see if there is at least less of this due to my tight control on souping it last night.

    It should not be this hard to do, other films are no where near this finicky.

    I am leaning towards this. I have 10 100 foot rolls of 25 I'll need to put on the bay.

    Nice handle, that is where I live...

    I had this with expired Fortepan 400 film.. It was a bad batch, there are posts here and elsewhere detailing it.. There were emulsion defects and every frame had specks in it, regardless of how you developed the film or handled it. The specks were visible when you viewed the negs through a loupe or made an enlargement. Very fine little specks and totally randomly spread about.

    I also use tap water and reuse my stop and fix. I usually don't filter. I do use a drop of photo-flo for the final wash.. Have you developed anything since? Particularly from the same batch of film?

    That's a misunderstanding, different film. The IR is going back to the shop for an exchange. I am going to shoot Rollei IR until this gets sorted out.

    I am souping a test roll of Efke 25 tonight, if it looks good, I will keep the bulk rolls of Efke.

    Is the junk on the film able to be felt, like sandpaper or sand or debris in teh emulsion? Is what you see on all films you process or only this specific film?

    It's getting late and I am not quite following what the stuff is on the film. Post a bit more on whether it happens to more than one specific film or if it is more than one. Or do you go a few rolls with no troubles and then it crops up again?
