Flash Mode — RPT: Stroboscopic Flash
With stroboscopic flash, a rapid series of flashes is fired. It can be
used to capture a multiple images of a moving subject in a single
photograph.
You can set the firing frequency (number of flashes per sec.
expressed as Hz), the number of flashes, and the flash output.
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.
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.
Stroboscopic flash can be used with"buLb".
●
If the number of flashes is displayed as "--", the firing will
●
continue until the shutter closes or the battery is
exhausted. The number of flashes will be limited as shown
by the following table.

Wireless Flash Shooting: Optic Transmission
This product is compatible with Nikon Creative Lighting System
(CLS). It can function as either an optic wireless master or slave
flash. As a master unit, it can control Nikon speedlights e.g. SB-
900 and SB-910 via wireless. As a slave unit, it can be controlled
by wireless signals of Nikon speedlights e.g. SB-900 and pop-up
flash commanders of Nikon cameras e.g. D7100/D7000/D800.
●
You can set up three slave groups for i-TTL autoflash shooting.
With i-TTL autoflash, you can easily create various lighting effects.
Any flash settings for the slave units on the master flash in i-TTL /
●
Manual / RPT mode will be automatically sent to the slave units.
So the only thing you need to do is to set the master unit for each
slave group without any operation for the slave units at all during
the shooting.
This flash can work in i-TTL / M / RPT / OFF flash modes when set
●
as a master unit.
