A motion picture camera is a device used to capture moving images, creating the illusion of motion when played back. It works by recording a series of still images, or frames, at a rapid rate, typically 24 frames per second for film. These cameras can vary in design and technology, from traditional film cameras to modern digital models. Motion picture cameras are essential in the film industry, enabling filmmakers to tell stories visually. They can be equipped with various lenses and accessories to achieve different effects. Notable examples include the Panavision and ARRI cameras, which are widely used in professional filmmaking.
