Photography is the art, science 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.
The result in an electronic image sensor is an electrical charge at each pixel,
which is electronically processed and stored in a digital image file for subsequent
display or processing. The result in a 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.
