so,

"back in the day", when "prints" were made, was it like we as still photographers make prints?

I totally understand the difference in latitude and compression rates of a neg-->pos vs pos-->pos system for reproduction.

but in the captions, when it mentions 'prints by deluxe', what does that mean exactly? surely they didn't enlarge EVERY negative, the hundreds of thousands, if not millions for a feature 90-120 minute film. but did they, or was it an automated process, with a machine?

thanks for all the help so far everyone

keep ideas coming, I'm enjoying this topic a lot!
