photographic film
Camera's recording medium
Photographic film is a thin, flexible material coated with light-sensitive chemicals that captures images when exposed to light inside a camera.
Until digital photography became dominant in the early 2000s, film was the standard medium for both amateur and professional photography.
Different films varied in sensitivity to light (measured in ISO or ASA), color properties, and grain characteristics.
After exposure, film requires chemical processing to develop the latent image into visible negatives or positives that can then be printed or projected.
