It is. A tilted frame pulls your sense of upright: psychologists have measured it since 1948 with the rod-and-frame test. In 2025, 21 people in a VR headset turned a rod until it looked upright; with the room tilted 15 to 20 degrees, they missed by up to three and a half degrees, leaning the way the room leaned.

Filmmakers call a tilted frame a Dutch angle. In The Third Man (1949), Carol Reed tilted so many shots that, he said, William Wyler sent him a spirit level for the top of his camera. A critic called it distracting; cinematographer Robert Krasker won the Oscar for black-and-white cinematography.

But does a tilt make you uneasy, as film schools say? We found no study that measured it. The pull on your upright is tested. The unease is a convention.

The rooms, the stand-ins and the test are our own models, built and lit in code.

Did the room feel wrong, or did you just lean?
