What Is Digital Photography?
Digital photography is a great new way to capture, preserve, and share your memories. Digital cameras work just like traditional film cameras, but with a few key differences. Like a film camera, they use a lens and a shutter. But instead of recording the picture on film, the images are captured with an electronic image sensor that converts the image instantly to a digital file, which is saved on a removable memory device. A key feature of digital photography is that the image you shoot can be viewed on a small screen on the back of the camera immediately or on your home computer later. It then can be printed at home, through an online photofinishing service, or at retail outlet such as Jessops. The images also can be instantly shared via e-mail, on a Web site, or in an online photo album.
