Instead of consistently standing in front of a camera and waving an LED bulb to make long-exposure light paintings, Josh Sheldon computerized the task with an exceptional photography rig that will take instructions straight from 3D animation software. The resulting animations, created using exact camera movements and robot-controlled lights, are like nothing you have ever seen before.
Light painting: there is something that hardly ever gets old. Waving light sources around in a long exposure photograph. Although the majority of light paintings are single images, a few artisans meticulously create frame-by-frame animations. This is quite complex when moving a light around by hand: it truly is mostly guesswork, because you will not see the results of your time and efforts until after the image is taken. But you may be wondering what if you can make the patterns extremely precise? What happens if you can actually model them in 3D? Josh Sheldon did just that!
He points out that each of the animations he made took between four and twelve hours to shoot, one frame at a time. Each frame is a long exposure, with the exposure being between one and three seconds. The machine performs the pre-programmed light painting and it’s later turned in an animation. Sheldon has been generous with his creation, sharing all the details concerning its creation on GitHub. Look at the entire process in the video below:
