 Digital Cameras

A digital camera is an electronic device used to photograph and store images in place of using the former photographic film used in the more conventional cameras.

With additions to the technology of digital cameras, many of them are now multifunctional, including the ability to record sound and videos. In the modern Western market they currently outsell the 35 mm cameras.

Digital cameras can be found in several categories:

* Video cameras: These are designed to record moving images.  Those used in movie and television production usually have many image sensors, usually one per color, which enhances the resolution.  The professional video cameras don't usually have a built-in microphone of VCR.

* Camcorders: These are the video camera of the amateur. They usually have a built-in microphone and a viewing screen to watch the video during recording and playback. Many of the new camcorders can now take still photographs, but even the low-end LPD takes better still photographs than the best of the camcorders. Some of the newer camcorders record directly to flash memory and transfer the data over USB or FireWire.

* Webcams: These are attached to computers for video conferences and viewing of those you talk to while on an IM or video phone call. They have full-motion abilities, while some have zoom abilities and microphones included.

* Movies: Some digital cameras have a movie capability that allows taking movies.

* Live-Preview Digital Cameras (LPD): These are cameras that use live preview on an electronic screen to allow previewing a photograph before you take it. Most digital cameras fall into this category.

Most digital cameras are also known as digicams. Characterized by ease of operation and focusing, the design allows for limited video capability.

The zoom ability of these cameras is quite a bit smaller than on the predecessor of film cameras. With and extended dept of field, objects that are further away can easily be in focus. This accounts for the increased ease of use.
