Digital Photography Tips - About Digital Cameras

By Dan Feildman

Photography has been reinvented through the use of digital cameras. Based on a "no film theory," digital cameras have created an entirely new era of photography where the information is stored as digital-bytes in the form of pixels. The pictures you have taken are stored directly on a digital card, inside your camera, safe and ready to view/ store/print. Since the photos are stored in digital form nearly every computer and other electronic viewing and printing device can read them too.

Similar to the conventional cameras we have used for decades, digital cameras use a series of lenses that focus the light and create the image that you want to capture. Using an electronic system, digital cameras do away with film completely, even though it is still capturing the light as with a traditional camera.

Digital cameras uses one of two sensors to capture the image, CMOS or CCD; CMOS sensors are less expensive and are easier to manufacture than CCD sensors. Because of this CMOS is used in less expensive cameras and generally does the same work as a CCD. More expensive models will typically use a CCD sensor. After becoming comfortable with digital photography you can usually see the difference between images captured with a CMOS and CCD system. A camera with over 6 megapixels will provide decent images as higher the resolution of the camera the better the photos that can be printed.

Since people don't want to wait for film to be processed and returned, the demand for digital cameras continues to grow. Since there is no longer need for mechanical parts to move the film cartridge the size of a digital camera is only determined by the size of the battery needed to power it. This feature has made it possible to manufacture easy to carry models and subsequently made them so popular.

Digital cameras are available in a variety of 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".
