I'm taking a medium/ large format b&w photo class and we're using Holgas first. I feel like an idiot, I'll blame my stupidity on sleep deprivation, but I straight spooled the film all the way to the end. How can I go about 'unspooling' it? I don't have access to a darkroom or light tight bag for awhile. Yes, I realize that this is the digital photography forum, but I was advised that I might get more help in here vs. the community forum.
