Assignment 1
Multiple camera shooting was established to be efficient and time saving, and if you did it right you would not have to edit it at all. Usually the director and assistant director would choose when to switch the feed from one camera to another. The multiple camera was used from 1936 onward and is still used today. The switch to a different camera was indicated by a device called a tally light. The usual shows it was used for is, sitcoms, talk shows, soap operas, game shows, and sports games.
