How to do Holopainting

We’ve all heard of hyperlapses, stop-motion, and light painting. But what is holopainting? It’s a newly invented technique that combines hyperlapse, stop-motion, and light painting with an extensive post-processing routine to create images that look like holographic paintings. Here’s how it’s done:

Thomas Pöcksteiner’s and Peter Jablonowski‘s university graduation project involved 24 Raspberry Pi computers and webcams to build a giant 3D scanner.

These individual computer and camera systems were arranged in a circle. Each made a photo of the subject in the center but at a delay of 83 milliseconds so the movement of the subject was also recorded in a bullet-time setup.

Each of the images then went through a painstakingly long process where the subject was cut out from the original background and placed against a solid black background.

The next process involved a light painting artist who painted the original images against the current camera position using a Pixelstick, which is a computer operated light painting stick consisting of 200 LEDs.

With camera positions meticulously maintained to match the previous shot, the team could mimic a holographic image that was entirely light painted.
