When you start fighting for the highest possible resolution in digital cameras, you usually count in mega-pixels. METIS Systems goes further: 4 giga-pixels in a single camera. The Digital Macro Camera 1015/C [PDF] is able to photograph 12 square meters at non-interpolated 254 ppi. (100 pixel per square millimeter).
This is a tool to make photographic reproductions of the highest possible quality and, contrary to what has been done by others, this is not a technique to stitch hundreds of images but a dynamic scanning directly included in the camera.
Italy seems to be the right place to do high-definition images these days.
