This photo shows how the strings of a guitar vibrate at high speed and twist in the photo. This image is based on the Rolling Shutter effect of a camera and the fast-frequency vibration of the guitar’s strings. Most modern cameras have rolling shutters instead of global shutters. It means that when shooting a picture, the camera's CMOS sensor scans and exposes the light in a row of pixels in order to receive it. When the guitar is positioned slightly vertically in front of the camera and the strings are plucked, the strings vibrate leftwards and rightwards at high speeds. When the camera’s shutter speed is adjusted to extremely high, the resulting image is hard to blur and becomes clear when moving at high speeds because the camera exposure time is reduced. Therefore, when the strings vibrate at a high speed, the displacement speed of the strings is faster than or equal to the scanning speed of the camera CMOS, resulting in the deviation of each row of pixel images on the CMOS from the previous row, and finally presenting such an amazing scene of strings twisting like jellies.
