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 an image 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 charge at each
pixel, which is
electronically processed
and stored in a digital
image file for
subsequent display or
processing.
