Dentsu London, the same ad agency that recently experimented with iPad light-painting, was recently hired by Canon to create a commercial for the Canon Pixma line of printers. They decided to create super close-up and super slow-mo shots of paint dancing by using sound, and created a rig that spins around the paint super fast to create a sense of motion as they shoot at 5000 fps. As you’ll see from the video, this is a great idea for still photos as well.
The resulting commercial can be seen at the end of the video. It’s stunning.
