Since 1974, this nonprofit art organization has championed experimental photo-based imagery beyond classic B&W prints and casual digital snapshots. Since moving into a spacious Market St gallery, Camerawork's far-reaching exhibitions have examined memories of love and war in Southeast Asia, taken imaginary holidays with slide shows of vacation snapshots scavenged from the San Francisco Dump and showcased SF-based artist Sanaz Mazinani's mesmerizing Islamic-inspired photo montages made of tiny Trumps.
