I just hang the 35mm roll to dry, weighted with a couple of clothes pegs or similar. 12 hours after processing, I cut it into strips, put it into sleeves and close the ring binder, thus putting a fair old weight on the sleeve. 12 hours later, they are fine.(posted 9664 days ago)If I don't put weight on the sleeve, the negs do curl badly, and nothing seems to take it out fully.
