Probably people who are interested in darkroom work figure out how to have their own, eventually. There are plenty of community college and art center darkrooms for people who want to try it out. I imagine that people either fail to remain interested or catch the bug and build their own. Or catch the digital bug.(posted 8830 days ago)Perhaps you can go to a local school or college and volunteer to run their darkroom. If they let you market it properly, it could be very fun and satisfying. But you won't make money (unless they decide to pay you!).
