Analog film larger than 35mm — typically 65mm or 70mm for IMAX and premium theatres. Unparalleled detail, expensive, limited stock availability.
Anyone who has held a 65mm camera in their hands immediately understands why these things inspire respect. The film stock itself is massive—about three times the size of standard 35mm—and the cameras weigh accordingly. You need specialists who know how to handle them, specialized magazines, robust tripods. On set, this means longer preparation, less flexibility, but in return, a picture quality that impresses even after digitization.
The practical reality: Large-format film was used for a long time almost exclusively for blockbuster cinema shots—spectacular sequences that were meant to justify the grand cinematic experience. Christopher Nolan swears by it because the grain structure and natural depth of field have a kind of presence that digital cameras struggle to emulate. But you don't just shoot an entire production with it—that would be economic madness. Instead, 65mm is used for hero shots: car chases, action sequences, scenic establishing shots where every detail counts. The rest is shot on 35mm or digital. This requires planning: Which scenes justify the effort?
The technical hurdles are real. Film stock is expensive, and its availability shrinks year by year—only a few labs still process 65mm professionally. You have to book months in advance. Storage is critical: temperature, humidity, everything must be right. And if something goes wrong mid-production, you don't have a quick solution. This makes large-format film a conscious, calculated decision, not a standard option.
What many overlook: The aesthetic added value only works if the material is also properly displayed on the big screen. 65mm negatives, reduced to 35mm or digitally converted, lose their advantage. It only makes sense if the distribution guarantees IMAX or premium formats. Otherwise, you're paying for quality that the audience never sees—a common situation in today's streaming world, where even blockbusters end up on phone screens.
