Would an increase in humidity help? Some of these are curled tight and require a little weight to keep them from climbing up. Where can I get plastic sleeves for negatives in roll form like Wolf Camera puts negatives in? These seem to be cut from a large roll and are lightweight. One other question. I have three rolls that were never developed. Any guess as to outcome if developed? They have been in a cardboard box in a closet for most of 50 years. Thanks for the input.(posted 8839 days ago)
