Light graffiti, otherwise known as light painting or light writing, is a technique first developed in the early 20th-century. When you create an exposure in a dark room or at night, you can move around a light source or camera as if it were a paint brush. Picasso even experimented with this technique towards the end his career. We're truly fascinated with the process, and think you should be, too.
