iPhone 4 video camera captures guitar string oscillations from inside the guitar [video]
A guitarist decided to video himself playing an acoustic guitar and, to be different, he stuck an iPhone 4 inside to capture the action from behind the strings. The results are really dramatic. The video has not been edited to emphasize the guitars oscillating strings; it is a natural occurrence with the iPhone 4 video camera. It is caused by the way the iPhone 4s rolling shutter works. Most consumer grade digital cameras do not take instant pictures; instead they scan the CMOS sensor diagonally from the top left to the bottom right. Fast moving objects create problems for this technique and produce these weird and wonderful distortion effects.
Take a look at the video after the break; it is definitely worth a few moments of your time!
