I saw this posted today at Lemonodor Auxiliary – Lia Halloran made this image (check out the others at her website) by tying a light to her wrist and using long exposure settings on her camera. But I can't figure out why it doesn't show HER running/skating around…is it because the light is so bright combined with certain settings on the camera? Or perhaps the image was processed after shooting? I don't know but I'll just enjoy the magic of the photo.
