How ‘Day for Night’ Artist Jim Campbell Reflected S.F. Back Onto Itself

High on a ledge inside Jim Campbell's Dogpatch studio sit three scale models of the hollowed-out apex of Salesforce Tower. The smallest, at eight inches tall, approximates what the top of the tower looks like from a little over two miles away-say, from the top of Alamo Square. The second, at 16 inches tall, is what it looks like a little closer in, from the Exploratorium. And the tallest, 30 inches, represents the view of the tower from within 3,000 feet (i.e., Red's Java House). "The danger zone," Campbell jokes-where you're looking up 30 degrees and start smashing into things.
