SET
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 on 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 speedlight 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 speedlight
• Stroboscopic flash is most effective with a highly reflective
subject against a dark background
• Using a tripod and a remote control is recommended.
• A flash output of 1/1 and 1/2 cannot be set for stroboscopic
flash
