Multi: Stroboscopic Flash
With stroboscopic ash, a rapid series of ashes is red. It can be
used to capture a multiple images of a moving subject in a single
photograph.
You can set the ring frequency (number of ashes per sec.
expressed as Hz), the number of ashes, and the ash output.
Calculating the Shutter Speed
During stroboscopic ash, the shutter remains open until the ring
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 ashes is 10 and the ring frequency
is 5 Hz, the shutter speed should be at least 2 seconds.

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