[GH85Carrera]

I used to work at a photolab and I was the guy in a DARK room operating the film processor. There is no safe light for color film and the darker the room the better. It was not just kinda dark, it was deep in a coal mine dark. I would often be in there for an hour or so and it was like being blind for an hour. More than a few times I "saw" something move when I was alone in a room with the doors shut. It was just my brain trying to see something. When I walked back out into just normal room light I had to squint because it was like walking outside onto full sunlight with new white concrete on the ground.

I would get all the film ready to put on the machine faster then the processor was capable of accepting so I had to just pace back and forth in a room with no light at all. There is nothing else to do when in 100% dark but think and pace. And yes, I walked into the wall more than a few times.
