To me it's like a lossy mp3 rip. Sad.
Digital films are so lifeless.
Working in a theater will make you very depressed about that state of things. I'm not very good as a projectionist, but I learned as much as possible and always tried to make the print look as good as it could.
IMAX and 70mm are similar but different. Not an IMAX fan myself.
2001 just in 35mm was overwhelming. I love the idea of Cinerama and will see something in it one day.
Data can never equal celluloid. Ever.
