Image of the Week: Scanning macro flowers by Kasi Metcalfe

Scanning macography on black and white large format. Basically a technique that gives total depth of field for macro shots. A specially designed machine is used where the object is mounted on a platform that moves slowly through a narrow slit of light from all directions. The shutter is left open and the camera is focussed at the one point the light touches the object, giving total sharpness as the object passes through that one point.
