It was really hard to find the way to organize my negative's mess, but one day I decided to straighten up my negatives, cd's and contact sheets. It was not an easy work, but it deserve it when you want to scan an old pic, check what film you used in that picture you like or just have organized the safest back up ever: the negatives.
