A film camera is a device used to capture images on light-sensitive film. Unlike digital cameras, which use electronic sensors, film cameras rely on chemical reactions to record photographs. When light enters the camera through the lens, it exposes the film, creating a latent image that can be developed into a visible photograph. Film cameras come in various types, including 35mm, medium format, and large format, each offering different image qualities and characteristics. They are often appreciated for their unique aesthetic and the tangible nature of film, which can produce rich colors and deep contrasts that some photographers prefer over digital images.
