This preview show (which I named—clever, huh?) affords you an opportunity to see some of the work that will be on display at Studio Nocturne (Oct. 13/14 at Fort Mason Center, details to follow). Calumet Photographic is at 2001 Bryant St. (at 18th St.), San Francisco. Hours for the show, which is upstairs, are Monday–Friday 8 a.m.–6 p.m. and Saturday 9 a.m.–5:30 p.m., through September 29. I was there for the hanging, and there’s some nice work up. It’s worth a look.
