Digital photography
Is form of photography that utilizes digital technology to make images of subjects. Until the advent of such technology, photography used photographic film to create images which could be made visible by photographic processing. 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 conventional photographic images.Sensors and storage

Sensors read the intensity of light as filtered through different color filters, and digital memory the digital image information, either as RGB color space or as raw data.

There are two main types of sensors: charge-coupled device (CCD) – photocharge is shifted to a central charge-to-voltage converters sensors ("Active pixel sensor")

Nearly all digital cameras now use built in and/or removable solid state Digital camcorders that double as a digital still camera use flash memory, discs and internal hard disks. For a time floppy disks and mini-CDs were used in early digital cameras such as the Sony Mavica range.
