For most of us who own cameras, we’ve at least heard of a darkroom, even if you’ve never been used one or been inside one. It’s been a part of photography for as long as photography has existed, and there are many still around today, despite the world going digital. A lot of people still shoot film, and there are plenty of darkrooms around the world you can hire, even if you don’t have your own.

One viewer, though, seems pretty confused as to what the hell this “red room” is. This viewer took to StackExchange to ask the question. Poor Ansel would be turning in his grave.
