Screen grab from Running on Empty video by Ross Chin. You can watch the video below.
The best kind of art makes us see the world differently.
Ross Ching created a video of something almost impossible to conceive: Los Angeles without cars. He used time-lapse techniques to capture the movements of clouds, people, traffic lights... But no cars. They were removed in Photoshop by layering enough still images that all parts of the image covered by cars could be replaced by parts from other pics where a car wasn't in that spot. The video is set to music by Radiohead, and you can see it below.
