Christian Erhardt of Leica, with Leica's X1 APS-C sensor compact camera. I took this picture in San Francisco's Chinatown during a totally random, chance meeting with Christian on the street. He was in San Francisco for a Leica workshop. Sometimes it's a very small world :-)

The original image was in color but B&W seemed appropriate for a Leica-related image so I converted it with the Photoshop Channel Mixer tool.
