San Francisco isn't Gotham. That's New York (or Chicago if you want to be wrong). San Francisco is too colorful, too weird, too positive and too future friendly to be the dark and gritty Gotham City. But Toby Harriman stripped the color of SF in this time lapse and man, the city by the bay looks pretty good when things go dark.
The time lapse, which Harriman calls Gotham City SF, shows various landmarks around San Francisco in black and white. It's like seeing a completely different city.
