Upright Bass Player Being Filmed at High Shutter Speed

submitted by pierrekrahn

From YT: Upright bass player being filmed by a camera with a high shutter speed. The strings are mesmerizing. Also, this clip is NOT in slow motion.

It's not really technically * timeshift as such, as the video isn't slowed down -the vibrations of the strings are frozen from high shutter speeds.
Fascinating stuff, though.

The strings would not look like this if filmed with a CCD with a universal shutter. This effect is from the rolling shutter in almost all modern CMOS-based camera sensors.

It's sort of an illusion, but not due to the optics of the camera, rather the temporal effect of the sensors.

vibrations are random, this is oscillation

With 20 years of interest in physics behind me, this is the best gut explanation of how stringed instruments work that I've even felt.
