The Mega Pixel Myth

What you *really* want are “better” pixels, not more of them. Contrary to popular belief, adding more pixels to the same size sensor isn’t going to help you very much. In fact, it may hurt. Why? It’s reallly quite simple: A limited amount of light gets through the lens and hits the sensor in your camera. It’s really quite small. At some point, if you add more pixels, those pixels aren’t picking up enough light to be useful. Instead, they’re making your photo noisier and reducing the quality. [on Smug Blog]
