Dawson's Creek - Dawson's Lens Cover
During the tenth episode of season 4 'Self-Reliance' Dawson is filming his documentary on Mr. Brooks' but due to a nurse's advice Dawson has decided to halt filming. He therefore put the lens cap back on his camera and turns to leave until he is persuaded by Brooks' to stay. Dawson then starts to film again with the lens cap still on; the front of the camera is visible in shot. The camera never leaves the shot and then when we see it from the front again the lens cap has been removed magically.
