This was a pretty cool project...
The picture was made last night using hand-held flashes and flashlights. When the camera shutter was open, about 1,000 volunteers painted the building with their flashes and flashlights during a timed exposure. The goal was to produce an image with even, shadowless light. This photograph was shot with a Nikon D3X with a 14 mm lens. The shutter was open for 15 seconds and the aperture was set at f11 at ISO 200. RIT
