In a studio or soundstage, the producers and directors will have to decide between a one- or three-camera shooting approach. Beyond the pilot, though, this can become a network decision. With a single camera, there is more control over the camera and editing work, allowing for a nice mixture of close-ups, wide shots and a lot of movement or activity. With three cameras, the scenes rely more on dialogue to help the story progress. Think about the differences between "My Name is Earl" (one camera) versus "Two and a Half Men" (three cameras).
