Photography is the art, science and practice of creating durable images
by recording light or other electromagnetic radiation, either chemically
by means of a light-sensitive material such as photographic film, or
electronically by means of animate sensor. 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. The
result in an electronic image sensor is an electrical chargeable each
pixel, which is electronically processed and stored in a digital image
file for subsequent display or processing
