oh, labs...you asked about those too. I don't know of any in the city but am certain there are more than a few. Perhaps, somebody who lives closer in will chime in? If you're shooting slides, Calypso Imaging is down in Sunnyvale - kinda a long way from SF but, worth the effort. Their prices are fantastic and they do fabulous work. (they have a huge Galen Rowell print on the wall at one end of the counter too ). There are few noteworthy labs across the bay in Oakland and Berkeley too...but, I get up that way even less than I do into the city.
