Finland-based photographer Janne Parviainen says, “You know you are totally and utterly mad when you are tracing a whole room with one LED alone in the middle of the night." He might refer to himself as "mad," but the results of his madness are super impressive. The series, titled “Light Topography,” was actually shot straight from the camera, taking as long as half an hour to create such long exposures. In the game of light-painting, Parviainen is on top.
