...rings that Saturn is known, and it was close-up pictures of those rings that stole the show last week. Within minutes of Cassini's arrival, the ship's camera had fired off 61 shots of the rings, and by 10 o'clock the next morning, wide-eyed Cassini scientists were showing them to the press. "I don't think we've ever seen structures like this before," said Porco...
...funny, but the Lebanese people seem to follow their real estate in this regard. I have spent many hours filming interviews with people from all over Beirut and its suburbs, asking them (through my Arabic-speaking friend) what they think of Americans. In front of the camera, most say things that give me hope for the relationship between the U.S. and the Middle East—things like, “I don’t associate the American people with what the American government does.” Once I switch off the camera their rhetoric changes.

...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 measure just 2.8 microns wide, whereas those on the Nikon D70 are 7.8 microns wide. (A micron is tiny...
Another factor affecting quality is the brains of your camera. A digital camera needs to have enough processing power to transform those raw data into a beautiful picture. The quality of your camera's lens is also important to ensure that your picture is properly focused and to pull in enough light to get a good exposure. "If you have a bad lens, the number of megapixels doesn't mean anything," says Atsushi Tashiro, a product-development manager for Fujifilm...
...find the camera that's right for you? Your best bet is to read independent reviews on sites like cnet.com dpreview.com and pcmag.com Then the next time someone brags about his new multi-megapixel digital camera, you can ask him how big the pixels are or what kind of lens he's got. Chances are, he'll have no idea...
