Getting Ready Shopping for the right model undoubtedly is more daunting than picking out an Instamatic, thanks to the technology industry's eternal love of jargon. The key specification for a digital camera is its resolution, or how fine an image it can produce. Resolution of cameras, like computer screens, is measured in pixels. A camera with a resolution of 640 by 480, for example, can snap an image containing 640 pixels, or dots, across by 480 pixels down, a total of 307,200 pixels. That level of resolution is fine for a computer screen but won't usually produce images sharp enough for printing.
More pixels mean more details in the images.
Eastman Kodak Co., Bayer AG's Agfa unit and other manufacturers offer similar megapixel models. This is important because you'll need the software to fine-tune and manipulate the pictures once they're in your computer. The Web can help with your research. Manufacturers' sites offer detailed specifications, while other sites publish reviews and tips. Prepare to spend some time getting familiar with the gear before trying out your digital toy on an important occasion.
