Dolly zoom

The dolly zoom is an unsettling in-camera special effect that appears to undermine normal visual perception in a way that is difficult to describe. The effect was invented by Irmin Roberts, a Paramount second-unit cameraman, and was famously used by Alfred Hitchcock in his film Vertigo, although it appeared earlier at the climax to his film Spellbound.

• The "Hitchcock zoom" or the "Vertigo effect"
• "Sam Raimi cam" or a "Jaws shot"
• A "zido"
• A "zolly"
• A "contra-zoom" or "trombone shot"
• More technically as forward zoom, reverse tracking or zoom in/dolly out

In the dolly zoom, the setting of a zoom lens is used to adjust the field of view at the same time as the camera dollies (or moves) towards or away from the subject in such a way as to keep the subject the same size in the frame throughout. In its classic form, the camera is pulled away from a subject whilst the lens zooms in, or vice-versa.
