HT1853 - The Disappearing Megapixels

Congratulations on your new 42 megapixel (or 60 megapixel) camera. You can now make giant prints. Good for you. But what happens to those megapixels if you don't make giant prints? What happens if you make a 13x19", or even a 17x22" print? All those captured and processed pixels get tossed out as superfluous data that is simply not needed.
