    Curled transparencies

    Hi,

    Hoping someone cane help. After developing and drying, my 5x4 transparencies are curled. Some more than others. It doesn't happen with any of my B&W negs. I've tried putting them in sleeves, leaving books on them for sometimes days but they still spring back. I'm using a Mod54 in a paterson tank. Using tetenal.

    Any advice?

    Thanks

    Is it any transparency emulsion, or just one film type?

    Also, is it possible to post a digi-shot of a curled sheet?

    Sometimes, what it actually looks like will trigger an easy explanation or solution from one of our local experts.

    It varies. I've had fresh velvia curl, expired ektachrome and expired velvia all do it. Tonight for example, I processed two velvia 50 (exp) and two Ektachrome 100

    Strangely enough, I'm having a problem with 120 roll film too. This is also happening with Ektar. I process at 100 deg, washes at 100 deg. I hang to dry in the shower.

    I've attached an image. Left to right. 100VS, 100plus Velvia 50 for the other 3. These were all processed at the same time.

    Those images provide excellent evidence for the forum jury.

    I think the springing back even after "weight treatment" is a telling clue.

    Are the sheets curled before you hang them to dry, or do they curl in the process of drying?

    Also, if you've ever used a vendor for E6 for the same batch of film, did you see the same curling?

    the film is staying curled from being curled while in your processor. Since the majority of labs use some sort of dip/dunk system with film clips/hangers, the film is kept flat. Mine do flatten out eventually and since I drum scan, the curl isn't an issue for scanning but a pain for viewing on a light box.

    roll film can be even worse. I have had one side almost touching the other a few times. With roll film I keep it under control a bit by clamping the end on both sides with something flat.
    Letting the shower run for a bit more than usual so the booth is very humid seems to work well too, but this might be a myth and a fluke on my part.

    Re: Curled transparencies

    Hi Heroique, the film is curled when it comes out the tank before drying. I haven't used a film lab for a long time so I haven't tested this avenue. I think all the 5x4 labs have gone where I live.
