Berg developed a specific photographic technique for this film. Through long exposures they recorded an iPad moving through space to make three-dimensional forms in light.
First they created software models of three-dimensional typography, objects and animations. They then rendered cross sections of the models, like a virtual CAT scan, making a series of outlines of slices of each form. These were played back on the surface of the iPad as movies, and the iPad were dragged through the air to extrude shapes captured in long exposure photographs. Each 3D form is itself a single frame of a 3D animation, so each long exposure still is only a single image in a composite stop frame animation.
Each frame is a long exposure photograph of 3-6 seconds. 5,500 photographs were taken. Only half of these were used for the animations seen in the final edit of the film.
There are lots of photographic experiments and stills in the Flickr stream.
