Tourists experience cities in a vastly different way to local residents.
Eric Fischer has created a series of fascinating maps of the major cities of the world from a database of geo-tagged photos.
The red bits indicate photos taken by tourists, while the blue bits indicate photos taken by locals and the yellow bits might be either.
