I saw these photos the other day and was totally blown away. I have seen light painting before but these eerie skeletons by the fantastic Helsinki photographer Janne Parviainen are the best I have ever seen.
Light painting is a special technique in photography when exposures are made at night or a dark room by moving the camera or a form of hand held light. In many cases the light source itself does not have to appear in the image. The first known photographer to use this technique was Man Ray in his series “Space Writing” created in 1935.
