Calculate shutter speed
In the process of stroboscopic flash, the shutter should be kept open until the flash stops. Use the following formula to calculate the shutter speed, and then use the camera to set it.

Flash number/flash frequency = shutter speed
For example, if the number of strokes is 10, the frequency of strokes is 5 Hz, and the shutter speed is at least 2 seconds.
In order to prevent the flash head from overheating and damage, do not take more than 10 consecutive stroboscopic shots. After 10 flashes, please let the flash cool for at  least 15 minutes. If you attempt to perform more than 10 consecutive stroboscopic shots, the flash may stop automatically to prevent the flash head from overheating. If this  happens, let the flash cool for at least 15 minutes.

• It is more effective to use stroboscopic flash in front of a dark background for highly reflective subjects.
• It is recommended to use a tripod and remote control switch.
• Stroboscopic flash cannot be set when the flash output is 1/1 and 1/2.
• You can also use “bulb” when stroboscopic flashing.
