Some of the most popular manufacturers include Kodak, Fuji, JVC, Hewlett Packard and Olympus. I think people tend to buy cameras by the name of the manufacturer. Once captured, digital photographs are already in a format that makes them incredibly easy to distribute and use. For example, you can insert digital photographs into word processing documents, send them by e-mail to friends, or post them on a Web site where anyone in the world can see them. Some cameras can even be connected to a microscope to display dramatically enlarged images on a large-screen television.
Digital photography is instant photography without the film costs.
