alt Hacker NewsI've seen non-IMAX 70mm referred to 5/70 because the image uses five perforations per frame; IMAX 70mm is then 15/70 because it uses fifteen perforations.
Digital IMAX is much bigger:

How much can we trust the "Reddit IMAX community"? The people heavily invested in a technology as their hobby aren't always the best sources of objective technical information; is /r/imax more of an "audiophile forum" or more of a forum of people who actually know their stuff?
