At first glance, this may look like a photograph of shelves in a supermarket. But look more closely and you may see a man painstakingly painted to blend in with the colourful background. Chinese artist Liu Bolin has become world renowned for his camouflage art. Liu uses a team of two assistants to paint the camouflage onto him to make him invisible, and each photograph can take up to ten hours to set up. In some cases, Liu has his assistants paint his body and then he remains extremely still until an unsuspecting passer-by happens to walk past.
