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.
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 the stroboscopic flash more than 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.
