San Francisco photographer Eric Staller uses light and architecture as a medium to create and design works of art. The artist made a name for himself in the 70s by creating a series
of long-exposure images shot in the streets of New York City. He set
the camera up on a tripod, and manipulated light in the frame to
make a futuristic array of patterns and colors in the dead of night. You can view more of Staller's work here for info.
