Japanese photographer Sohei Nishino documents cities by compiling photos into maps in his series titled Diorama Map.
He walks all across each city he visits, capturing thousands of shots per location. He then constructs photomontages that reflect how he remembers the mapping of each place, based on the most notable sights of the area.
It's an ongoing project, adding more and more cities, but he already captured one of my favourite cities. Swiss capital Bern. And since I know Bern very well I can tell you that Sohei has some damn good memory! This map is close to perfection.
