London's landmarks have been visited by some rather illuminating vehicles - a series of light-painted supercars. The images are the latest work of Marc Cameron and photographer Mark Brown. The duo are secretive about their exact methods but say they use a process of reflecting and refracting LED light to create outlines. Every detail of the vehicles is planned precisely before setting a camera on long exposure to catch the light painting. The entire process can take up to four hours.
