STORY-TELLING UNIT: 180º rule and Crossing The Line

Where you position the camera in a scene is where you place the audience.

Placing a camera over the shoulder makes the audience an observer.

Placing the camera opposite person places audience within the action.

180º rule

If the camera is kept on behind the line - the characters stay facing the correct ways - the characters stay on their right side of the screen.

Only cross the line if the audience is involved in the action i.e. they see the camera move.
