IMAX
The IMAX MSM 9802 is a 65mm motion picture camera shooting on 15-perforation IMAX film stock, producing the largest film negative in commercial cinema. Its images, projected on IMAX screens, achieve a resolution and immersive quality that no digital system has fully replicated.

Community note
“Nolan is the most prominent advocate for IMAX film; "The Dark Knight" (2008), "Interstellar" (2014), "Dunkirk" (2017), and "Oppenheimer" (2023) used IMAX cameras extensively. Documented in many interviews.”
