By Shane Brewer


Point and shoot cameras have been a regular site anywhere you go. For anyone who is getting ready to get a first SLR camera, or maybe you have been looking to exchange one you've already got, it is wise to familiarize yourself with the information of just what exactly makes one camera not the same as another and choose the one that is best for you. Listed here we are going to cover just about the most major factors in picture quality.

Not unlike a film digicam, the digital camera has got a lens that brings light into center on a bed of light fragile material. On the digital camera, that light delicate material is a circuit bed known as the "CCD." The CCD has exactly the same duty as film in a film camera and the camera lens permits light to drop onto the CCD which is then converted into a digital graphic.

The grade of the lens can make a substantial difference in the resolution of that picture. Really cheap digicams could even employ a piece of plastic for the camera lens, which should typically have an uneven surface and light transmission. This really is exposed in the photograph though will not be a major problem for any security camera or a web cam.

Better quality cameras may perhaps have ground-glass lens and high-end digicams will even have interchangeable lenses just like high-end film cameras. The camera lens still performs the top role of pulling light clearly to the CCD surface for a distortion free photograph.

A CCD additionally offers an fascinating advantage to the digital camera. You may electronically adjust light sensitivity to raise contrast, take pictures in shadowy light, or maybe take black and white, sepia or infrared and ultraviolet light shots with the press of a button.

Because any of these photographs are preserved as the same data in the memory card, a digital camera can offer unparalleled ability without having to reformat picture types. You cannot assume all cams include these features built in, but they're options you'll see in a few digital cameras. While the possibilities are cool, ask yourself if that is a feature you must have in a digital camera.
