This past year, people in the United States bought twice as many digital cameras as film models, according to the Photo Marketing Association. Next year a bigger change may loom: Cell phone cameras are projected to sell even more than regular digital cameras.Posted by jackhodgson at December 20, 2004 12:43 PMThe larger story, though, is how people are using their digital cameras differently from the film models. Consider the photos snapped by National Guardsmen showing abuse of Iraqi prisoners at Abu Ghraib prison, which were e-mailed widely and shown on national TV. Or the Nashville man who helped police nab the mugger who jumped him at a carwash, by using his cell phone camera to photograph the mugger as he fled.
