Light graffiti - Jan Wöllert and Jörg Miedza

Based in Bremen, Germany, Jan Wöllert and Jörg Miedza - the minds behind Light Art Performance Photography - have been working together since 2007. Strangely, neither are full-time photographers; Jan is a PA while Jorg is an office-based worker. They've created this series of 'light graffiti' which utilises a host of light sources, from flash lights and bike lights to blinking LED lights, to 'paint' a picture straight onto the camera lens. The images are created with long exposure cameras in the dark. Sometimes the exposures run on for longer than an hour.
