About the series

These works depict trajectories of flight in and around the Berkeley, California, captured throughout 2020.

How it works

The process begins by capturing a moving subject on video, using a camera on a sturdy tripod. I then extract the individual frames from the video to produce an image sequence. Then, with pixel-processing and computational techniques, the frames are sequentially superimposed, to make a progression that reveals the otherwise invisible tracks that the moving subjects leave behind.

Special thanks

Check out this blog post where I explain some recent improvements to my video processing toolkit and how some help from a couple of friends made it possible.
