„A single strip is 17 pixels high, and was taken from just under the dome of City Hall, across to the base of the Millennium Tower, the turquoise building on the right side of Market St. The exposures were made at the rate of one a minute, for a total time of 2 hours 2 minutes. The final piece is a 6.4 megabyte image.„
