Photography is the science , art , application and practice of creating durable images by recording light or other electromagnetic radiation , either electronically by means of an image sensor , or chemically by means of a light-sensitive material such as photographic film . [1] Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure . With an electronic image sensor, this produces an electrical charge at each pixel , which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image , which is later chemically "developed" into a visible image, either negative or positive depending on the purpose of the photographic material and the method of processing . A negative image on film is traditionally used to photographically create a positive ima...
