It’s easy to lose yourself in Barbara Vaughn’s photographs, on view this week at San Francisco’s Dolby Chadwick Gallery. They toe the line between digital image and Abstract Expressionist painting — at first glance, you never know if it’s one or the other. Those undulating strokes and arty swirls à la Gerhard Richter or Jackson Pollock are actually water reflections off the Aegean and Adriatic coasts taken with a long-lens Nikon D7000. Can’t make her current show? You can catch Barbara’s work again at Sun Valley’s Friesen Gallery starting July 30th.
