Remember the video of guitar strings oscillating, caught by an iPhone sitting inside a guitar? Turns out you can capture this outside a guitar if you just apply a ton of lights. It makes sense, as you're monkeying with the rolling shutter, which can then capture the oscillations of the guitar strings as they are plucked.
It's great fun to watch, and tipster Mike Salovich tells us he wound up using 2600 watts of industrial light to capture this effect. He also points out how important camera orientation is, as it will maximize the rolling shutter effect. Check out the video to see what he's talking about.
