What is the structure of black and white film?

The structure of black and white film primarily consists of a series of still images captured on a light-sensitive medium, typically film stock, which is coated with silver halide crystals. When exposed to light, these crystals undergo a chemical change, creating a latent image that is later developed into visible shades of gray, ranging from pure black to pure white. The film is then projected at a specific frame rate, usually 24 frames per second, to create the illusion of motion. This classic format emphasizes contrast, texture, and composition, often resulting in a timeless aesthetic.
