I’ve updated this map a bit, added some, sadly removed others. For the next version, I will probably change it to “Photography San Francisco,” and add camera stores, galleries, etc. If I’m missing anyplace, drop me an “ask.”
Unrelated: Google removed “My Maps” from the latest Android version of Maps, which is disappointing, because I make these custom maps for any city I visit to walk around with, and search for other people’s maps to use. For example, my Tokyo map.
