About This Course
Digital photography uses cameras containing arrays of electronic photo detectors to produce 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, electronic publishing, or digital printing.
Digital photography replicates the process of traditional film photography, but it uses an electronic sensor, rather than film, to capture images. These digital photographs are stored on a memory card, and their resolution is measured in megapixels.
