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.
