Motion picture cameras are devices used to capture moving images on film or digital media. They work by recording a series of still images in quick succession, which, when played back, create the illusion of motion. These cameras can vary in size and complexity, from small handheld models to large studio cameras used in professional filmmaking. The technology behind motion picture cameras has evolved significantly since their invention in the late 19th century. Early cameras, like the Kinetoscope, used film strips, while modern cameras often utilize digital sensors for higher quality and easier editing. Today, filmmakers can choose from a wide range of cameras to suit their creative needs.
