The camera or camera obscura is the image forming device and photographic film or a electronic image sensor is the sensing medium. The respective recording medium can be the film itself, or a digital electronic or magnetic memory.
Photographers control the cameras and lens to exposure the light recording material (such as film) to the required amount of light to form a "latent image" (on film) or "raw file" (in digital cameras) which after appropriate processing, is converted to a usable image. Modern digital cameras replace film with an electronic image sensor based on light sensitive electronics such as "Charge couple devices" (CCD) or " complementary metal-oxide semiconductor" (CMOS) technology. The resulting digital image is store electronically, but can reproduce on paper or film.
