Radiohead frontman Thom Yorke describes this song as his most political work. "Harrowdown Hill," is part of Yorke's solo album, "The Eraser," which released in August 2006. After seeing the short films of Chel White, Yorke sought him out to direct his next music video.
White, who is co-founder of Bent Image Lab in Portland, OR, chose to incorporate an innovative technique that he and the rest of the Bent artists had been researching previous to this project. Dubbed Smallgantics, the technique takes footage of large objects (rivers, factories, city skylines) and makes them appear as though they are actually miniatures. In "Harrowdown Hill," Chel used aerial footage from the pacific north west to be miniaturized using Smallgantics.
The process involves splitting the footage up into several vertical planes that move back over the perceived z-axis, or into the image along its perceived depth. These planes are then affected with varying degrees of blur to simulate a shallow depth of field. If done right, the amount of blur increases smoothly as it moves along the planes of the image. Next, these levels of blur are animated to simulate a change in focus or to compensate for the forward movement of the camera.
