Helsinki, Finland-based photographer Janne Parviainen has been light painting since 2008, and recently created series of experimental photos showing a technique he calls Light Topography. Using a single LED light for each image, he carefully traces over every surface in the scene while the camera’s shutter is open. Fully tracing a room can take as long as half an hour. The resulting light outlines provide a trippy look at what each space contains.
Some of the photographs remind us of the movie The Matrix:
All the photographs in this series were done entirely in-camera, with no special CGI or trickery applied afterward. You can check out the rest of the images in this series in this Flickr set.
