Brodie, who has a background in fine art and design and is a graduate of London’s Ravensbourne College of Design, performed a number of tests to determine how best to obtain clean silhouettes. Ultimately, he and Meyers settled on an approach where the dancers would be shot against bluescreen while holding iPods. The wires Brodie would painstaking paint into each frame in post. “They wanted the wires to have a specific look and thickness, so I drew them in frame by frame,” Brodie explained. “That allowed me to give them a smooth movement that would have been impossible to achieve with real wires.”

Brodie also applied color and texture to the iPod units held by each silhouette. “We wanted the iPod to stand out so I pulled color and texture of the face plate from the live action and applied it to the silhouette,” he explained. “That approach didn’t work for the back of the unit, so I painted it white. The iPods therefore have a different treatment depending on which way they are facing in the frame.” - Source
