These images are the work of artist and camouflage expert Liu Bolin.
Born and raised in China, he's become known as the 'Invisible Man' and his work has been featured in museums around the world, including Beijing, Shanghai, Paris, and New York.
Right now, his work is on display at Galerie Paris-Beijing in Paris and features a number of new images where Liu essentially hides in urban settings - part of his 'Hiding In The City' project.
Incredibly, he does all this without using special effects or Photoshop. Instead, his assistants help Liu cover himself in paint, using photos of the scene behind him as a guide.
As artnet.com explains "he often takes up to 10 painstaking hours painting his own body to match a portion of the chosen site, before photographing himself standing within the scene as he blends into the background."
The site goes on to say "according to the artist, his Camouflage works are metaphors for the feeling of anonymity and ostracism he encounters as a Contemporary artist in China."
Designboom.com says "he is able to model for hours without moving."
In 2005, Chinese officials shut down Liu's studio.
After that, his work became more political, in what he calls "a silent protest... a protest against the state."
With his work, Liu says "My intention was not to disappear in the environment but instead to let the environment take possession of me".
According to thisiscolossal.com, Liu suggests the works are a "statement regarding damage caused by economic and urban development."
The Paris show runs through March 10th. You can see more of Liu's work here on the website for Eli Klein Fine Art in New York.
