"photographic film"の定義と意味

What is "photographic film"?

Photographic film is a light-sensitive material used to capture images in photography. It consists of a flexible base coated with a layer of light-sensitive chemicals that react to exposure to light. When the film is exposed to light through a camera, it records an image, which is then developed through a chemical process to create visible photographs. Photographic film comes in various types, including black-and-white, color, and specialty films, and is used for both still photography and motion pictures.
