Now for the Fun Stuff! Computer Gadgets and Gizmos 276 Techno Talk A digital camera, like a scanner, is built around a CCD (charge-coupled device). When you snap a picture, the shutter opens and bombards the CCD with light. The CCD converts the light into electrical impulses, which then are applied to a magnetic storage medium such as a disk or PC card. Shopping for a digital camera is nearly as complicated as shopping for a computer. Prices range from $100 to more than $1,000 and features vary widely. You need to consider resolution, color depth, memory, flash options, battery life, storage options, zoom features, and the method used to download photos to a computer. Special features, such as voice annotation, an LCD viewfinder, and optical zoom, come at a premium price. As with any big-ticket item, try before you buy, and read current reviews.
