Digital cameras are marketed these days much like cars: the more horsepower you've got the better, thus the more megapixels your camera's got, the better. A pixel is a tiny square dot called a picture element. It's the sensor that actually captures an image. Most digital cameras contain at least a million of them, so you'll be dealing in megapixels.
Digicam marketing has become an arms race of megapixels as companies rush new models to market. The more megapixels, of course, the higher the camera price and the greater the profits for the manufacturer. Marketeers want you to believe that megapixel content is the standard by which all digital cameras should be judged, but dozens of other variables are just as important. The quality of the lens optics is crucial. Higher resolution produced by pixel content isn't synonymous with higher print quality.
Image clarity can be affected as much by lens quality and other design factors as by the pixel content. A laboratory evaluation found that a 2-megapixel camera produced better prints than several 4-megapixel models tested. Other factors to consider are the type of media storage provided and its replacement cost; the projected battery life (still the weakest link in all digicams); the image censor's dynamic range and color response; and the type of LCD viewfinder the camera uses. So before ever buying a digital camera, just ignore the hype and buzz about megapixels.
