Hi - Apologies if this is too basic for this forum, but I've just developed two rolls of B&W 35mm on a steel reel and have gotten pink blotches on about 1/3 of the pictures each time. I have some experience with plastic reels and never had this problem before; this is the first time I've tried steel. Is this a problem with how I've loaded the film on the reels, or is this a chemical problem...? If anyone could please advise me on how to avoid this I would appreciate it! Thank you!
