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 digitzed 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.

Famous quotes containing the word photography:
“Too many photographers try too hard. They try to lift photography into the realm of Art, because they have an inferiority complex about their Craft. You and I would see more interesting photography if they would stop worrying, and instead, apply horse-sense to the problem of recording the look and feel of their own era.”
—Jessie Tarbox Beals (1870–1942)
