Dolly Zoom
Tags: dolly counter zoom, dolly zoom, reverse tracking shot, the hitchcock zoom, trombone effect, vertigo effect
A dolly zoom combines a track-in or track-out movement with the apparent movement of a zoom in the opposite direction. Depending on whether it is a dolly out/zoom in, or a dolly in/zoom out, either the background shifts towards the foreground or away from it.
The respective zooming direction and additional perspective changes caused by the camera movement produce either a special dizzying or oppressive effect.
A dolly zoom is also variously known as:
- Dolly counter zoom
- Reverse tracking shot
- The Hitchcock zoom
- Vertigo effect
- Trombone effect
