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.
