It’s very cool when people mix traditional instruments with new technology – Make sure you watch the strings! I love this music with real-life visualization!
In this video, an enterprising young man places his phone inside an acoustic guitar, points the camera out of the sound hole, and begins to play.
He didn't expect to see the guitar strings turn into wacky, wavy and shapely lines. It's crazy.
The effect seen in the video is called rolling shutter. Reminiscent of a strobe light, the rolling shutter effect does not capture all elements of an image at exactly the same time, but portrays each frame in its entirety during playback.
It’s the same effect that explains this seemingly nonsensical footage of airplane propellers flying off the actual propeller and disintegrating in thin air.
Also, notice that after embedding the iPhone in the instrument, the guitarist goes outside for the actual demonstration. That’s because backlighting is critical to capturing the effect.
I've seen videos of spinning propellers and bike wheels that are equally as beautiful and mystifying.
