The annual SF Camerawork benefit auction took place on November 13th this year, with an ad for Gawain Weaver conservation services on the back cover. In addition to classic images and work by well-established photographers, there were many Bay Area photographers represented, such as Ben Nixon (Shasta National Forest, gelatin silver print from wet collodion negative) and Chris McCaw (gelatin silver print from his sunburned series). I have enjoyed this photo auction the last few years since returning to California, and we were happy to contribute in a small way by placing an ad on the back cover of the auction catalog.

Thanks also to the Yosemite Museum, National Park Service for permission to reproduce the before and after treatment images of their Carleton Watkins albumen print “Vernal Falls, 300 ft, Yosemite, 1861.”
