Hey all
Having some frustration with the SB-910. I know it can strobe (aka repeating flash mode) beautifully off-camera, but won't strobe when it's on the hotshoe. RTFM isn't helping, as nowhere does it say that that function is limited in anyway. All other modes like GN, M, TTL etc all work fine onboard. Just not the strobe. I tried too with the flash set as the master flash and STILL nothing.
Anyone have any ideas?! |

RTFM again? :-) Just kidding.
Is it called RPT? Does it have to be on manual mode? Is the shutter open long enough for all flashes? I've the sb900, on shutter priority mode, 1/6 shutter speed, RPT at 1/128 intensity, 7 flashes at 10 hz and it works for me... Different flash I know, but it might work all the same...

It's probably what Niall said. The shutter speed needs to be slow enough to allow the flash to finish the strobe burst. You may have to go all manual to get there.

depending on the flash, but this is for most flashes, the fastest shutter that you can have is 1/250. and thats risking it. usually 200 is good. do you have a wireless reciever/controlor?
besides that i got nothin... |

| I have a 900, and I can fire it on camera in On mode. Then hit menu to change it to RPT and set your desired number of flash times. I don't have a 910 to mess with though, but I think the interfaces are pretty similar? Keep in mind, you can only fire at 20 Hz. |

yep it is called RPT, and I always shoot manual. I may be asking for too many hz. It still fires, just one shot instead of several...which is kinda sorta what I want...and yes, Sofia, do have a remote radio transmitter.
Anyway all gear packed up as leaving soon, so will tackle it in earnest when I get home. Thanks much all for your input! :-) |

I'd say try a slow shutter and a slow frequency. If it's really quick it might look like one big one...

Yep all you guys were right, I had too high a shutter speed and slower frequency. Duh. Must be my blonde roots! I had way too much fun in my hotel room playing with the flash on strobe ;-) |

I seem to be having the opposite problem of the original poster: I can't seem to get the SB-910 to do stroboscopic (RPT flash) work while off-camera?
For the 'ON' switch position - i.e. sitting in the hot shoe on the camera, it has a RPT (repeating flash) mode. This works great for Stroboscopic flashing but 'ON' mode doesn't work off camera. (Unless I'm missing something.)
For the 'REMOTE' switch position - it has no RPT capability unless triggered by a second SB-910 being used as a master on the camera. (Though if you change the setup to SU-4 (optical slave) then the flash can repeat when triggered by the camera's built-in RPT capability. (But I don't want light coming from the camera direction.)
When in MASTER mode - it can trigger RPT flashes in remote cameras, but this is again, on camera. And it seems to be a lot of money to buy two SB-910s to achieve single-point off-camera stroboscopic.
I must surely be missing something?
Thanks. |

Sorry, I hadn't seen your response to this thread, and now, it being so long overdue, you probably won't see mine, either...but for those who are curious...
ETA: I forgot about these when I initially posted- SG-3IR. They may do the trick, though I've never used them.
No, you're not missing anything. You need to either use another commander flash (SB800, 900, 910) or an SU800 or dumb slave (SU-4) to do optical triggering. Otherwise you will need to get a radio trigger of some kind. The SU-800 is cheaper than a flash and has some other good commander abilities, but it is a pretty specialized piece of gear and somewhat expensive for what it does, especially since it mostly only works for line of sight and under shorter distances with Nikon's CLS system. For the type of application you're doing, I'd recommend radio triggers as they are more versatile long term.
