Digital Photo Recovery

Digital photography uses an array of electronic photodetectors to capture the image focused by the lens, as opposed to an exposure onphotographic film. The captured image is then digitized and stored as a computer file ready for digital processing, viewing, digital publishing or printing.

Until the advent of such technology, photographs were made by exposing light sensitive photographic film, and used chemical photographic processingto develop and stabilize the image. 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 other photographic images.

Sensors and storage

Image sensors read the intensity of light, and digital memory devices store the digital image information as RGB color space or as raw data.

The two main types of sensors are charge-coupled devices (CCD), in which the photocharge is shifted to a central charge-to-voltage converter, and CMOS or active pixel sensors.

Nearly all digital cameras use built-in and/or removable solid state flash memory. Digital tapeless camcorders that double as a digital still cameras use flash memory, discs and internal hard drives. Certain 20th century digital cameras such as the Sony Mavica range used floppy disks and mini-CDs.

Multifunctionality and connectivity

Except for some linear array type of cameras at the highest-end and simple web cams at the lowest-end, a digital memory device (usually a memory cardfloppy disks and CD-RWs are less common) is used for storing images, which may be transferred to a computer later.

Digital cameras can take pictures, and may also record sound and video. Some can be used as webcams, some can use the PictBridge standard to connect to a printer without using a computer, and some can display pictures directly on a television set. Similarly, many camcorders can take still photographs, and store them on videotape or on flash memorycards with the same functionality as digital cameras.
