Camera shots are used in filmmaking to convey different perspectives and information. Some key shots include the establishing shot which orients the audience to a setting from a distance, wide shots which show a full human or object to emphasize scale, and crane shots which allow movement around a scene from one viewpoint. Close-ups focus intently on details while extreme close-ups magnify details beyond normal human vision. Point-of-view shots place the audience in a character's perspective while shot reverse shots alternate between characters to imply they are looking at each other.
