Film vs. digital: the most contentious debate in the film world, explained - Vox
"If I can't shoot on film I'll stop making movies," Tarantino said on Los Angeles radio station KCRW's show The Treatment. He added, "If we're acquiescing to digital projection, we've already ceded too much ground to the barbarians. The fight is lost if all we have is digital, DCP presentations. To me, that's just television in public."
Just what is Tarantino talking about here? When someone pushes his glasses high up on his nose, raises a finger, and creaks, "Actually, film is…" chances are he’s about to explain the difference between analog and digital filmmaking.
Once upon a time, all movies were shot using machines that would take 24 photographs or "frames" every second and instantaneously leave a negative of those images on a filmstrip. It would then be treated with chemicals and displayed for showings by running the reels containing these strips of pictures through a projector. (Some cameras can also take more than 24 frames per second — see motion smoothing, above — but this generally produces an image that looks too real to our used-to-24-fps eyes.)
