Yes they were!! When I was a kid I worked in a photography store, they sold all kinds of cameras, equipment, and 24hr. developed everything. With a car stereo store next to it my check was gone before I got itIn the mid-80s, those places were BUSY!!! The day after Christmas was INSANE.
. Color was done by machine and B&W in the dark room. They would do all the developing for the local police and sheriffs. I was one of the guys who didnt mind developing the police photos (all B&W). Some didnt have the stomach for it. After all these years some of those photos are still scratched into my brain!
