Current print stocks have gotten away from the rem-jet as that eliminates a wash step, and water is hard to come by in Southern California where many film labs are located. for the same reason soundtracks are now Cyan, and every theater had to switch to newer sound heads that use a red laser or LED light source. The newer Digital tracks are also cyan.
Ugh! I had to change out an entire 20-plex. You have to just about gut the sound head to do it.
It took my boss and I two days to complete the job.
Most Theatre prints are scrapped soon after the film leaves the theatres.
Unfortunately a large portion of theater prints are scrapped as soon as they ENTER the theater! Most megaplexes hire teenage monkeys to work for minimum wage, nowadays.
I've seen entire three-hour features dumped on the floor. That's 15,000 feet of film trashed in less than a second.
Here's a picture of a movie projector where the operator started the machine but didn't check to be sure it was right before he left. He just pressed the button and went downstairs to chat up the popcorn girl. (The guy in the picture is the theater technician who was called in to clean up the mess.)
The moral of this seemingly off-topic story?... An hour's worth of movie film is almost 1,000 rolls of film for my 35mm camera.
As much as I hate to see film get damaged for no good reason, I have to admit that clowns like that keep Kodak in business.
And, as long as they are in business I can keep shooting pictures on film. Right?
