Digital photography, as opposed to film photography, uses electronic devices to record and capture the image as binary data. As such, the images can be displayed, printed, stored, manipulated, transmitted and archived using various kinds of digital technology, including personal computers and the Internet. On the digital camera itself it is possible to view the recorded images immediately and to delete the ones not wanted.
Digital cameras now outsell film cameras and include features that are not found in film cameras such as the capacity to store many more images on a memory device than on a roll of film, the ability to record video with sound and functions to automatically and manually make edits to images and even delete images. Digital cameras in various forms are now found a great number of devices ranging from PDAs and mobile phones to vehicles through and even in space on the Hubble Space Telescope.
Multi-Functionality 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 flash memory; floppy disks and CD-RWs are less common) is usually used for storing images, which may then be transferred to a computer later. Digital cameras can take pictures and sometimes additionally record sound and video. Some can be used as web cams, 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 memory cards.
