I have yet to shoot a film in 1.33:1 but I certainly plan to do that. Particularly in B&W.
To me, 1.33:1 or 1.43:1 or any kind of box-y aspect ratio makes me feel less claustrophobic especially if it’s framed with extra head space. This preference grew the more I watched full IMAX footage or certain frames from films like “Cold War”. I find the look very pleasing to the eye.
I always thought it would lend the film a kind of calm steadiness. Where you’d linger on shots or just put the camera on a tripod and observe.
My love for a taller frame also comes from my love for still photography. This is how I view my images at the moment so why not carry it into films?
