Calculating the Shutter Sped
During stroboscopic flash, the shutter remains open until the firing stops. Use formula
below to calculate the shutter speed and set it with the camera.
Number of Flashes / Flash Frequency = Shutter Speed
For example, it the number of flashes is 10 and the firing frequency is 5 Hz, the shutter
speed should be at least 2 seconds.
To avoid overheating and deteriorating the flash head, do not use stroboscopic flash
more than 10 times in succession. After 10 times, allow the camera flash to rest for at
least 15 minutes. If you try to use stroboscopic flash more than 10 times in succession,
the firing might stop automatically to protect the flash head. If this camera happens,
allow at least 15 minutes rest for the camera flash.
