The Master was the first motion picture in 16 years to be filmed on 65mm format using Panavision’s System 65 camera. Around 85% of the film was shot in this format, with the rest shot on 35mm. The last full-length motion picture to be shot in 65/70mm was Kenneth Branagh’s 1996 adaptation of William Shakespeare’s Hamlet. The decision to shoot in 65mm came from a desire to replicate the look of photos taken by vintage Pressman cameras, which use large-format 4x5-inch film. This also led to the use of the narrower 1.85:1 aspect ratio (65mm has a native aspect ratio of 2.2:1). Director Paul Thomas Anderson initially suggested shooting the film in VistaVision, and test footage was shot in that format, but the shallow-focus effect was not pronounced enough (x).
