Wired has a fascinating article detailing some of the revolutionary advancements in high-speed cameras. The article details a new show called "Time Warp," "whose premise is to make the ordinary extraordinary with one trick: slowing it down." The high-speed cameras used for this are incredibly expensive, costing more than $100,000, but they can stretch a few seconds of action into several minutes, allowing us to see details within the action that were previously unknown to us.
Wired has several great videos illustrating this powerful technology, including a video utilizing the high-speed camera underwater to capture beautiful images of a surfer riding a powerful wave. That video is below, but be sure to check out the rest of them here.
