When buying a digital camera, many people focus on just one factor: megapixels, the more the better. But that's not the whole story. Lens quality, image-processing capability and even the size of the pixels can all have a greater effect on how your pictures turn out. "The number of megapixels," says Bob Sobol, an image scientist at Hewlett-Packard, "is relatively unimportant...
...were to crack open your digital camera, one thing you would find is the image sensor, a tiny silicon chip about a half-inch wide embedded with millions of pixels tightly packed together. When struck by light, each pixel generates an electric current that is converted into the digital data that make up your picture. But not all pixels are created equal, and some cameras use larger ones than others. For example, the pixels on the HP Photosmart R707 are just 2.8 microns wide, whereas those on the Nikon D70 are 7.8 microns wide. (A micron is tiny?1/24...
...river booms through my dreams. We're through. Early the next day we're off again, stiff but elated. Wet socks, dirt in our cups of tea, even the plastic bags have long ceased to matter. First off is the ABC rapid, named for the raft full of camera equipment lost there by an unlucky TV crew, courtesy of a partly submerged log. No problem. By now we're at ease in our rafts; the blue one steered by Pat and dubbed the QE2 for its superior buoyancy and comfort; the Red Devil under Dan's control, a little leakier...

"The number of megapixels," says Bob Sobol, an image scientist at Hewlett-Packard, "is relatively unimportant." What the quantity of megapixels (each one equals 1 million pixels) does determine is how big you should make your prints. For most consumers, a bottom-of-the-line, 2-megapixel model is just fine...
...European PC maker Medion, the $599 PC (plus $299 for the 14.1-in. monitor) features a 2.66 GHz Intel Celeron processor, a 40-GB hard drive, 256 MB of memory and a CD burner. And there's an array of matching accessories, including a 1.3-megapixel digital camera ($79) and a game controller...
