The home page of Alan Bamberger's ArtBusiness.com, an art services site, is peppered with phrases like "dispute mediation" and "consulting on buying, selling, donating." In other words, it's boring. But turn your attention to the left column, click the undistinguished link called San Francisco Art Openings, and revel in the full glory that is Bamberger's nightlife. A couple times a month, he heads to gallery openings — nearly all of them, or nearly all that deserve attention — with his camera in tow, and snaps away, later posting hundreds of images on his site. He captures not only the art, but also the people looking at the art and, often, the artists looking at the camera, simultaneously fulfilling our competing desires to look at hipsters and look at paintings. He also writes judicious comments about the work, a mix of art lingo and blunt talk on whether the stuff is any good. The photo captions are minimalist gems, often just "Art," sometimes followed by Bamberger's version of high praise: "Like it."
