Cameras can vary from small to very giant, a complete room that is kept darkish while the thing to be photographed is in one other room the place it is correctly illuminated. This was frequent for reproduction photography of flat copy when giant movie negatives have been used . Photographers management the camera and lens to “expose” the light recording materials to the required amount of sunshine to form a “latent picture” or RAW file which, after acceptable processing, is transformed to a usable picture. Digital cameras use an electronic picture sensor primarily based on light-sensitive electronics corresponding to charge-coupled gadget or complementary metal-oxide-semiconductor technology.
