photography - choose a jigsaw puzzle to solve

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 . 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 image on a paper base, known as a print, either by using an enlarger or by contact printing . Photography is employed in many fields of science , manufacturing (e.g., photolithography), and business , as well as its more direct uses for art , film and video production, recreational purposes, hobby , and mass communication .
