Look closely. Very, very closely. In each one there’s an invisible man, usually the artist Liu Bolin himself. These are not digitally modified photographs or made by photoshop.

He is the Liu Bolin a Chinese artist known for taking photographs of himself, painted in order to blend in with the background. Liu works on a single photo for up to 10 hours at a time, to make sure he gets it just right, but he achieves the right effect: sometimes passers-by don’t even realize he is there until he moves. This series is called "Hiding In The City".

He graduated from the Sculpture Department of Central Academy of Fine Arts in Beijing. The talented Liu Bolin says his art is a protest against the actions of the Government, who shut down his art studio in 2005 and persecutes artists.
