    A question from a friend:

    "Trying to flatten some old 35mm B&W negatives, high quality heavy stock, no sprocket holes, that have been allowed to sit, curling, for at least 60 years maybe more. They don't want to go flat, I tell ya. Any ideas?"


    He has tried simply pressing them for a few days with no success.

    Over to you, Brains Trust...

    might be risky, but you try wetting them again and hanging them with wieghts

    or sandwiching them inbetween glass sheets and see if you can scan them first

    would the scanner not press them flat or is it a 35mm holder?

    He has tried 'squashing them' for a few days without success.

    He is using a Canon 9950F scanner, which apparently has special holders for the film, but the film is so curled up it jumps out of the supplied holders.

    I was thinking of suggesting he soak them in isopropal alcohol, but I do not know if the curl is caused by the base or the emulsion.

    Sticking them under heavy stuff doesnt work.

    Hot water is the easiest way, take 2 slides of glass (4x6 picture frame glass) put the negatives in between the glass so their flat (might want to wet it with cold water first so the glass sticks together), sit it in the hot tap water for approximately 1 minute.

    Take it out, even the worst unruly kodak gold 100 negs will now behave and be flat.

    If it doesn't have sprockets, its not 35mm. It's probably 127.
