What is a black-and-white silent film made of?

Black-and-white silent movies are shot with movie cameras.

The earliest cameras only had the function of taking pictures. They used countless black-and-white films to record images, and no other equipment recorded sounds, so the images played by projectors were all black-and-white and silent. It was not until 1889 that Edison in the United States invented a camera that could drive the phonograph, and the era of talking movies began.

The earliest black and white camera in the world;

1874, Jules Jean Sang of France invented the camera. He wound the photosensitive film on a toothed film supply reel. Under the control of the pendulum mechanism, the film supply tray moves intermittently in the circular film supply box, and the pendulum mechanism drives the shutter to rotate. Every time the film stops, the shutter will open for exposure. Janssen connected this camera to a telescope, which can take a set of photos of planetary motion at the speed of one per second. Janssen named it a photographic gun, which is the originator of modern movie camera +Y6R.
