Photography is the science, artwork, program, and practice of producing durable images by recording mild or alternative electromagnetic radiation, either electronically using an image sensor, or by way of a jelly-like substance like a photographic movie.

Typically, a lens is utilized to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera through a timed vulnerability. With a digital image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital picture file for following processing or display. The effect with photographic emulsion is an undetectable latent picture, which can be later chemically “developed” into a visible picture, either negative or positive based on the aim of the photographic material and the procedure of processing. A negative image on film is traditionally utilized to photographically make a positive picture on a paper base, known as a printing, either by using an enlarger or by touch printing.

Photography is employed in several areas of science, manufacturing (e.g., photolithography), and business, as well as its direct uses for art, film and video production, recreational purposes, hobby, and mass communication.
