The Establishing Shot
Film directors use different types of camera shots for specific purposes. An establishing shot is an image shown briefly at the beginning of a scene, usually taken from far away, that is used to provide context for the rest of the scene. One purpose of the establishing shot is to communicate background information to the viewer, such as the setting—where and when the rest of the scene will occur. It also establishes the mood or feeling of the scene. Due to the context that the establishing shot provides, the characters and events that are shown next are better understood by the viewer.
