Rather than view digital cameras, scanners, and printers as isolated accessories to home or office computers, they’ve taken an approach more oriented to users interested in photography for the sake of the pictures themselves. When you select a particular media type, the motor whirs, and the front throat of the scanner reconfigures itself to accept the chosen media: On the earlier PhotoSmart scanner, we observed a minor problem with the calibration process, which showed up in very dark areas on some of our standard images.
