Digital camera
* All digital cameras consume a lot of energy and a lot of batteries
  - have auto-focus
* Many digital cameras are like low-cost film cameras when it comes to the lens.
* Many digital cameras come with an LCD
  - software for cropping and rotating snaps
  - provide adjustable resolution and file compression settings
* Many digital cameras use an aperture that is variable
  - standardized removable memory cards
* Most digital cameras are mega-pixel models that create images with a million or more pixels
  - similar to point and shoot cameras
  - small enough to fit in a purse, and many can fit in a pocket
  - can serve as Video cameras
  - come with a built-in flash
* Most digital cameras come with an LCD display on the back of the camera
  - electronic flash unit built in to their body
  - image-enhancing software
  - software to edit and manage the image files created by the camera
  - compress the image
  - contain an energy buffer that safeguards against memory deletion
* Most digital cameras have a built-in flash
  - an optical view finder
  - at least low, medium, and high modes
  - fully automatic operation
  - zoom lenses
  - run at one full image every few seconds
  - save images to a removable memory card
* Most digital cameras use flash memory cards to store the images that are taken
  - good quality optical glass
  - the gray card to balance their colors
* Some digital cameras allow manual control of aperture and shutter speed.
* Some digital cameras are capable of taking pictures at variable resolutions
  - notorious for taking pictures that are a little too dark
  - come with a lightweight protective case
  - employ a combination of electrical and mechanical shutters
* Some digital cameras have a non-removable memory chip embedded within the camera for storing images
  - what is know as digital zoom
  - look like ordinary cameras
  - use multiple CCDs to capture red, green and blue values
* allow people to take pictures.
* are a reality for consumer and professional use
  - electronic devices
  - generally compact, but only a couple are pocket sized
  - hot for every age
* are ideal for making quick photographs for the Web
  - taking panoramic images
  - in much demand as simple hunting-like tools for gathering images
  - notorious for eating lots of power
  - one area of consumer electronics that are particularly difficult to design
  - similar to computers in that the amount of memory is very important
  - small, fast and convenient and are decreasing in cost
  - terrific, too, for capturing pictures as data
  - very expensive
* built-in exposure meters try to balance the image exposure to produce a medium value.
* capture razor-sharp images and shoot video, too.
* do have their drawbacks.
* don t handle contrast as well as conventional film.
* eat batteries alive
  - batteries, even rechargeables
* enable people to transmit family pictures over the Internet in the blink of an eye.
* have LCD displays, like miniature television screens
  - a tendency to over-saturate colors
  - an LCD screen as the viewfinder
  - applications in both the consumer and business market
  - tremendous applications for communicators
* measure resolution in pixels, a point of colored light.
* offer a film-free way to post images directly after they're taken.
* operate very well without artificial light.
* produce images that approach the quality of film.
* provide digital pictures
  - instant pictures that download to a computer and viewed in a heartbeat
* require storage disks, or downloading onto parent computers.
* save digitized images in a memory cache, rather than on film
  - images on internal memory chips or on floppy disks instead of on film
* tend to be more complex in their operation than analog cameras.
* use alkaline batteries at a shockingly fast rate
  - batteries at an alarming rate
  - color wheels or color matrix CCDs to capture color information in the image
  - computer memory instead of film to hold their images
* use light-sensitive chips to capture their images
  - electronic sensors in place of film
  - many different file formats
  - memory flash cards to store images
  - other storage media for the images
  - outside sources of light
  - significantly more power than traditional cameras
* work best on still images
  - differently than traditional camcorders
+ Metadata: Computer science :: Photography
  * Digital cameras allow people to take pictures. Some cameras, espcially camera phones, have GPS and can include the location in metadata.
  * Most digital cameras can serve as Video cameras. Some have a direct link to another computer where the data may be stored.
