Calculating the Shutter Speed
During stroboscopic flash, the shutter should remain open until the firing
stops. Use the formula below to calculate the shutter speed and set it with
the camera.
Number of flashes
~
Firing frequency (Hz) = Shutter speed
For example,
if
the number of flashes
is
10 and the firing frequency
is
5
Hz,
the shutter speed should
be
at least 2 sec.
