Digital photography
Digital photography uses an array of electronic photo detectors to capture an image focused by a lens, rather than exposing photographic film. The captured image is digitized and stored as a computer file ready for digital processing, viewing, publishing or printing. A digital camera stores pictures and video electronically instead of on film. Digital SLR cameras operate similarly to traditional SLR cameras but store images digitally on memory cards rather than film. They offer advantages like live previews, unlimited reusability and the ability to capture video.
