Since 2010, San Francisco photographer Shawn Clover has been working on a striking series of then and now composite photos of the 1906 San Francisco earthquake. To create the series, Clover collected archival photos of the earthquake’s aftermath. He then replicated the photos himself, down to the location, camera position and focal length (to the best of his estimation). The resulting composite photos hauntingly combine stark images of the earthquake’s devastation with modern scenes of life in San Francisco.
They are missing some of course, and even more obvious, they don't have a contact email to help them out, tell them of cars they've missed, and send them the photos. Damn, I hate it when it's impossible to help someone out because they aren't smart enough to leave an email address.
