Some Information on Digital Cameras

By Dan Feildman

Digital cameras have reinvented photography. Based on "no film theory," digital cameras have started a whole new era of photography where the information is stored as digital-bytes in the form of pixels, which we all know, are tiny colored dots represented by ones and zeros. And the camera keeps the pictures, you have taken, safe and ready to view/ store/print. As the captured pictures are stored in digital form, almost every computer and other electronic viewing and printing device can read them too.

Similar to conventional cameras, digital cameras also work with a series of lenses that focus the light and creates the image that you want to capture. Using an electronic system, a lower specification Digital camera does away with film although it is still capturing the light as with a traditional camera.

CMOS sensors are less expensive and are easier to manufacture than CCD sensors. As such CMOS device is used in cheaper cameras and does the same work as a CCD. In comparatively expensive models, the system uses a CCD sensor. A Digital camera user can see the difference between images captured with a CMOS and CCD system. A model with over 6 megapixels will provide decent images as higher the resolution of the camera the better the photos that can be printed.

As people don't want to wait for the film to be processed and returned, the demand for Digital cameras continue to grow. Because of the lack of mechanical parts the size of the Digital camera is only determined by the size of the battery needed to power them. This feature has made it possible to manufacture easy to carry models and subsequently made them so popular.

Now a days Digital camera is available in various types such as Digital camera, Underwater Digital camera, Ip camera, Hidden or spy camera, Mini camera, Polaroid camera,Camera phones.

Daily more models/systems with the latest technology are coming to the market. Naturally people need a place where they can view latest models and that too at affordable price. To find them all at one place where information is updated every minute, and every item is available at the prices you desire/offer you can do an internet search using the keyword "compare digital cameras". - 15437
