Frequenzy of the bass strings and high shutter speed of the camera lead to this suprising string-wobble footage.
There is no slowmo applied to the take. Sound is original.
video was filmed with a Canon 5D MarkII , Nikon 50mm lens on 1,8f.

Neat how you can clearly see all of the partials in the string's vibration.
There's some cool stuff on vimeo
you can line up your bass strings with a televsion screen and see the same thing. hold your bass fretboard up with the strings profiled against the screen and pluck a few with different frettings. oh yeah, the tv must be on. ;)
I've done that, it's pretty wild. iirc, an A# is almost the right frequency to see a 'standing' wave.
Back in the CB craze days, I had a car with a long whip antenna on the rear bumper. One night while parked under a street lamp, I happened to swat the antenna as I passed by and watch the a similar display - when whipping it back and forth, I could see 20 antennas, all of which appeared to be stationary. It's all based on the light wavelength...and in the original above, the shutter speed of the camera.
You see, physics is fun
this dovetails nicely with my noodling in front of the television theory. ;)

Closing one eye also helps seeing the effect.
OK, I just posted this on my Facebook profile. That is really cool Dave. Thanks!
