Jay Huber told me about this. It's a book called Empty L.A., which consists of photos of Los Angeles with no people in it. A special effects technican named Matt Logue is responsible…and I'm guessing what he did was to shoot multiple photos of busy areas, then use Photoshop or something of the sort to combine unpopulated segments of many pics. However he did it, the result is mesmerizing, especially if you're familiar with these locations in their usual, human-filled states. Take a look at the preview and maybe order a copy.
