Film buffs adore tracking shots the way the Guinness Book of World Records adore a hot dog eating champion. But tracking shots accomplish a lot more than meets the eye. As with Orson Welles' B-movie masterpiece, "Touch of Evil," the opening shot remains one of the most famous examples of a sustained tracking shot. Not only does it execute a glorious 3:30 shot in one stroke, but it becomes more than just a visual novelty.
Tracking shots lock the subject in a graceful choreography of camera and scenery, where the actors dance with the DP. While a hot dog champion is still a hot dog champion (but we still think they're cool).
