Armed with a digital camera and inkjet printer, San Francisco artist Michael Koller is in the process of producing a unique photographic study.
He has taken thousands of sequential photographs of building elevantions along a 30 mile continuous route through San Francisco.
By editing these images to join up seamlessly he is producing one single continuous image.
Like many innovative art projects, this takes advantage of techniques that were previously unavailable. This is a project that would be almost impossible without digital cameras and imaging software.
