Digital photography uses an array of electronic photodetectors
to capture the image focused by the lens, as opposed to an
exposure on photographic film. The captured image is then
digitized and stored as a computer file ready for digital
processing, viewing, digital publishing or printing. Until the
advent of such technology, photographs were made by exposing
light sensitive photographic film, and used chemical
photographic processing to develop and stabilize the image. By
contrast, digital photographs can be displayed, printed, stored,
manipulated, transmitted, and archived using digital and
computer techniques, without chemical processing. Digital
photography is one of several forms of digital imaging. Digital
images are also created by non-photographic equipment such as
computer tomography scanners and radio telescopes. Digital
images can also be made by scanning other photographic images. A
digital camera (or digicam) is a camera that takes video or
still photographs by recording images on an electronic i
