The dolly zoom, also known as the Hitchcock shot or Vertigo effect, is a mesmerizing camera technique used in movies like Vertigo or Jaws.It plays tricks on our perception by making the background seem to stretch or compress dramatically while the subject stays the same size.It's created by combining camera movements of moving the camera forward while zooming out, or moving the camera backwards while zooming in.The dolly zoom effect creates a surreal perspective distortion that amplifies the emotional impact of a scene, drawing viewers into the moment.
