Why Resolution Is Important

Buy.com Tip: The total number of pixels on a CCD or CMOS doesn't necessarily determine the number of pixels used to record an image. With an 8MP camera, 8 megapixels equals 8 million pixels. And when you're recording the details of a scene with 8 million little pieces of information - instead of only 300,000 pieces - you get a much sharper, more realistic picture.
