I am not aware of any single frame picture at a shutter time of
1/250 of 1/500 of a second which shows anything other than
either a short straight linear motion (image stretched into a
short line) or a slight curve (image of a light turned into a
"banana" shape).

The "loops and whorls" that are "fingerprints" of complex hand
vibration turn up in relatively long exposures (0.1 sec to
several seconds). Most of the loopy hand vibrations I have
analyzed have occurred in movies or videos where the frame rate
is 10/sec to 30 /sec and the loops take several frames fo
complete.
