    Some films curl/cup, others don't.
    all the Rollei film I shoot dries dead flat, summer or winter, hot or cold, humid or not.
    all the Tri-X I shoot cups, summer or winter, hot or cold, humid or not
    All the GP3 I shoot curls up like a pig's tail, summer or winter ... ok, you get the idea

    So is it possible to re-wet or re-wash and dry it again at a different temperature to fix the curl? Or once curled never fixed?
    An awful lot of electrons were terribly inconvenienced in the making of this post.

    f/64 and be there.

    I don't know. I haven't tried that.

    In the past uncut complete 35mm film lenghts were packed in slide- screw-on top canisters a bit like those film cartridges are sold in. Though the former enabled to grip the roll .

    You might roll a processed film (with rest of the leader out), lay a U-bent paper strip around (to facilitate getting the fillm roll out again without forming a helix) and insert in a current canister with the free ends of the paper strip on top.

    The only film I ever have bad curl with is Foma and it's Freestyle derivatives; with these films I reverse roll it for a few days.

    You know, I'm not sure I gave all the relevant details. I'm asking about 120 roll film in this thread.

    Amazingly enough, I have never ever got curled 35mm films with Foma or its re-branded films (Arista EDU). It might be because of my tap water or the room temperature. Who knows... On the other hand, Tri-X ALWAYS gives badly curled films.

    From my experience, films that don't get curled: Kodak 125 Plus-X [discontinued], all Ilford films, all LegacyPro films [discontinued], Fomapan 100, 400 as well as Arista EDU 100 and 400, Kentmere 100. Even Lucky SHD 100.
    Films that get curled: Ultrafine Plus 100, Kodak Tri-X, Neopan SS, Agfa APX 100.

    I dry in a UT100 Durst dryer(its only a simply clear plastic square tube with zips and with fan assistance on top) using fan assistance at ambient temperature only for about 20 mins then leave hanging overnight in still ambient air. I keep a weighted clip in the bottom throughout and have always found that the films be they Kodak, Ilford, Fuji always dry flat

    Twenty years ago the lab I had processed my 120 films shipped them back to me rolled in 6 inch boxes protected with a long plastic sleeves. When I went to scan them 3-4 years ago, it was a pain. It was hard because of the curls. Now when I have a lab process them, they cut them in 3, 3, 2 and 2 images strips and placed in a glassine negative page when shipped back to me. That's their standard practice where I go although other labs still rollm them. That's nuts! I asked for 4, 3 and 3 but they didn't have those size pages. They stay really really flat this way making it easier to scan at home on my flat bed scanner. If it's negative film I sometimes ask for a contact print that can only be done by cutting the film into strips, regardless. Of course, I don't know what outside scanner labs want. But I can't imagine they wouldn't accept cut lengths although there may be higher scan charges.

    As an aside, why do you want to scan all the pictures?

    It may not matter depending on the scanning method, drum or flex tight will handle the curl. Contact the lab.
