The shoot is it: the moment of truth. This is when the preparation and work of all contributors is finally put to the test. The shoot can bring out the worst in actors: Their voices can get louder, their gestures more, and their movements more flowing. Single camera shoots is so costly to shoot that the producers more or less try to keep the camera and all the associated equipment working all the time. Each time the camera is moved to a different position, or is shooting a section of a scene in a different size shot, it is called a setup. One can expect to go through anything from fifteen to forty setups in a day, depending on the complexity of the shot, whether it is outdoors or in a studio, and so on. People sometimes disparage good actors, precisely because of their skill at making a difficult, technical sequence appear easy and ordinary.
