    How to straighten old negs?

    I am currently going through all my father's old medium format and 35mm negs and scanning them into the computer for him. Many of them he has never seen bigger than a contact print.

    Two of the rolls have been stored since 1957 and 1960 respectively in their old screw top tin canisters. Consequently they are like a pair of Slinkys! I have them hanging at the moment with a small clothes peg on the bottom of each to weigh them down, in an attempt to straighten them.

    Is there another method I could use without damaging them? They are both Ilford FP3 Panchromatic.

    Hanging them probably isn't a bad start. You could also cut them into strips, put them in neg sleeves, and put some weight on them.

    Thanks David, putting them in neg sleeves is the final intention, unfortunately they will become almost unmanageable if I cut them before they are reasonably straight. I am wary of mis-handling and damaging them. As soon as the weights are removed they spring right back into a tight little curl!

    I did a fair bit of this while in the archive. Assuming the base is polyester and not nitrile it can be done. ROll them on a processing reel and give them a god five minute soak in plain old water, then dip in photoflo, then hang them with the clips at the bottom. SHould do the trick. if the base is nitrile your SOL that stuff curls no matter what.

    Never had to do anything like this, but how about a soak in water followed by normal drying?

    I did think of giving them a bath. How long for? A few minutes? Overnight?

    What works somewhat is to take them out and roll them in reverse and put them back in the cans for a week. Not perfect, but I did 20 rolls this way enought to put them in pages. Then weighted down the pages flat.

    I use a method mentioned above. I place the film in a negative sleeve, place it on a flat, hard surface and then stack books on top for a couple of days.

    That seems to work great for most film.
