Light painting is a 125-year-old art form where long exposure cameras capture the path of light, rending a sometimes other-worldly image. In 2011 Finnish artist Janne Parviainen produced a series of light paintings called “Light Skeletons” in the snow. When artists use a moving light source as a paintbrush, amazing things can happen.
