Film terminology: A track and zoom shot is a particularly effective camera technique involving the simultaneous use of a tracking shot and a zoom. The great film director Alfred Hitchcock is credited with inventing this technique.

To create the shot, the camera is moved away from the subject, (along a dolly track), as the camera lens zooms in. If co-ordinated correctly, this combination of techniques results in the subject remaining the same size in the shot, but with an accompanying change in perspective.

Famous examples of the track and zoom technique include:

• 'Vertigo': Shot looking down the stairwell in the mission
• 'Jaws': Chief Brody spots the shark from the beach

The technique also works the 'opposite' way, (zoom-out/track-in), but has a different 'look').
