Rolling shutter effect on kalimba tines shot on Canon 5D Mk II. Rolling shutter happens on CMOS sensors when the shutter speed and the object moving speed (frequency in this case) are close because of progressive picture reading (top to bottom).

  • @kalimbamagic what you see is not nodes and harmonics but rather the tine in a different possition each at each line.

  • The unpainted tine just to the left of the central painted tine is C. The C has some great flubbery motions in the video. The frequency of that C is 261 Hz.

    Now, the first overtone is something like a factor for 2.6 times higher => 679 Hz.

    SO, with 1/4000 s ==> 4000 Hz, you are getting some really high overtones (ie, lots of "nodes", or several up and down waves across the tine.

    Cool! -Mark
