What happens when you drop an iPhone 4 into the sound hole of a guitar, position it just so, and then pluck the strings? Take a look at this video to find out.
Reminding us of that Les Paul Google doodle we showed you last month, this is not what guitar strings are really doing when you’re strumming away.
The strings look wavy because the iPhone‘s rolling shutter isn’t exposing the entire string all at once, but in a slightly different rate from their vibration. It’s an effect similar to the way spinning wheels look when shot on film — as if they’re spinning backwards.
Want to shoot a video like this yourself? Here are some tips from “justkylevids,” the talented guitarist who shot this video:
You must have the strings brightly backlit to get the camera to capture at such a high frame rate (pure conjecture). You can see how the effect fades when the buildings come into view.
Use a pencil [to position the iPhone inside the guitar]
This was used with the front facing camera, try the back camera, it may capture better!
