- deep_merge 2y agoYes, it’s an even larger format than traditional 70mm. The cells are physically larger. Anecdote: Nolan worked with Kodak to invent black & white IMAX film for Oppenheimer. https://www.kodak.com/en/motion/blog-post/oppenheimer/ https://www.kodak.com/en/motion/blog-post/oppenheimer/
- bradgranath 2y agoThe film is run through the camera & projector sideways, allowing for a larger frame to be laid down on the same stock. https://secureservercdn.net/198.71.233.183/gkz.aeb.myftpupload.com/wp-content/uploads/2015/04/IMAX-70mm-35mm-comparison.png https://secureservercdn.net/198.71.233.183/gkz.aeb.myftpuplo...
