Martin Gabriel Pavel and Czech artist Marek Kučera‘s project had one simple aim. “Daily Portrait IV Berlin 2015-2017″ consisted of one camera and 381 naked Berliners, mostly strangers who took photographs.  Once Martin had taken a picture of Marek, he then passed the camera on, so that he could find a subject to photograph and after he finished, then that person took the camera and kept the chain rolling forward etc.  This intriguing and interesting social experiment hopefully will give birth to a book which they are currently have a crowd fundraiser for, but meanwhile here are some of the stunning natural photographs below.
