A manufacturer that takes digital pictures of prototype products, then e-mails them to customers for approval. They used to do everything by snail mail. With digital cameras, they can shave weeks off production schedules. Like all things digital, cameras are changing rapidly. Quality has increased as dramatically as prices have decreased.
Digital cameras measure resolution in pixels, a point of colored light.
The more pixels, the better the quality of the image. Their images look the best, especially when printed. Something to consider is the higher the resolution, the bigger the image file. Most of the newer cameras come with small removable memory cards, like Compact Flash or SmartMedia cards. These allow you to keep taking pictures without having to offload pictures to a computer.
