This was shot on July 4, 2014 from the rooftop of a friend’s condo. I get the entire 40′ long, flat space to myself! And I take advantage of the full length. The cameras are Hasselblad 500Cs, outfitted with 150mm lenses. They are triggered by a wired remote devised by my genius friend, James Baker, who owns the condo. There is an article in the 1.2014 issue of STEREOSCOPY detailing what goes into the planning. See:
