Whether you are shopping for a Sony Cybershot, Nikon or any other type of camera, the quality of the picture is measured by the megapixel resolution of the camera. In simple terms, a pixel is the smallest bit if information with which a picture is taken, and an image is comprised of millions of these tiny bits which create shapes, colors, and shades. A megapixel represents 1 million pixels, thus an 8 megapixel camera would be comprised of 8 million pixels.  In general, a camera with 8 megapixels is one of the highest resolution cameras on the market today.  A camera with even 4 megapixels can still produce an image of such high quality that it can scarcely be determined as different from an 8 megapixel picture to the human eye.

Eventually digital camera technology will advance to the point where it will no longer be necessary to advance the amount of megapixels because it will be unnecessary to have an image where you can examine individual pores on a person’s face.
