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.
Analog photography is photography that uses a progressively changing recording medium, which may be either chemical process based (e.g., photographic film or plate) or electronic (e.g., vidicon or CCD sensor). For more than a hundred years, this was the only kind.
Digital video is a representation of moving visual images in the form of encoded digital data. This is in contrast to analog video, which represents moving visual images with analog signals. Digital video comprises a series digital images displayed in rapid succession.
