    With the dry air here in Colorado, film curl is a menace. I know a guy with a Kindermann rapid film dryer for sale. Would this help with film curl or make it worse? Would I be better off just using a humidifier?

    Are you drying with your film hanging with a weight in the end. That will help.

    Yes, I am. It curls along the length of the film like long trough and a weight won't stop that. I don't have an operational darkroom yet so I am still scanninng. Newton rings are a big problem. A guy who used to run a lab around here said he used to always have a humidifier going and when people would bring film in for enlarging, it would sometimes take a couple days to get the film to relax and flatten out.

    Also - what kind of film? Some curls more than others. HIE was dreadful. I always cut the curly stuff, put it in film sleeves, and flattened in my neg binder before using.

    Dry the film in the bathroom after you have the bathroom steamed up from a shower. That will help reduce the curl.

    Sly - Usually TMax 100 or 400.
    Sirius - This bathroom is rarely used for showering, but we do have an extra humidifier to simulate it.

    A film dryer will make it worse and faster too. :sad: As others said, you need humidity to lessen the curl. 40-50% is ideal for drying film. The dryer it is, the more the curl.

    FB paper too

    In the summer time, I have super curly FB prints. Slow drying makes FB prints flatter.

    I have a copy of Eliott Erwitt's book, Personal Best. It must weigh about 20 pounds. After my negs are dry I sleeve them and press them under the book for a day or two. Works every time... but unfortunately, being under Eliott's book for a couple days hasn't improved my images!

    I have the same issue. Nothing seems to help. For me, it takes months of storage for film to flatten out.... Tmax, Tri-X, Plus-X, everything curls. Strangely enough, Delta3200 does not curl....

    Yes, but my house is always air conditioned. So it is actually 40% RH during summer and dryer in winter....

    I just sleeve and weigh them down as well. Works well and is fine in my experience. With a more humid environment, like with a room humidifier or in the shower, the drying time increases, and if your area is even slightly dusty, you negs may dry with dust on them.
