Digital photography is a form of photography that uses cameras containing arrays of electronic photodetectors to capture images focused by a lens, as opposed to an exposure on photographic film. The captured images are digitized and stored as a computer file ready for further digital processing, viewing, digital publishing or printing.

Until the advent of such technology, photographs were made by exposing light sensitive photographic film and paper, which were processed in liquid chemical solutions to develop and stabilize the image. Digital photographs are typically created solely by and computer-based photoelectric and mechanical techniques, without wet bath 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 printed photographic images or negatives
