I shot a pack of PZ Cool from IP while on vacation. I bagged them in an Ilford black bag (for 5x7 paper). I guess I brought some humidity back from the beach, because several of them are stuck together now. I took two that were stuck and tried some light steam. They came apart easily, but spots seem to have formed on the pictures now -- even the one that wasn't stuck to anything, which I wasn't expecting. Neither one was torn or damaged from being stuck though. Any ideas how I can get the others apart without causing more problems? They were stored front to back -- i.e. the front of each image was placed against the back of the other. Thanks.
