Multi: Stroboscopic Flash
With stroboscopic flash, a rapid series of flashes is fired. It can be
used to capture a multiple images of a moving subject in a single
photograph.
You can set the firing frequency (number of flashes per sec.
expressed as Hz), the number of flashes, and the flash output.
Calculating the Shutter Speed
During stroboscopic flash, the shutter remains open until the firing
stops. Use the formula below to calculate the shutter speed and set
it with the camera.
Number of Flashes / Flash Frequency = 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 seconds.

10 times in succession, the firing might stop automatically
to protect the flash head. If this happens, allow at least 15
minutes’ rest for the camera flash.
