Actually at times neither one is going off. Having a hard time figuring that out. It is sparatic.


Are you giving them enough time to recharge between shots?

One more thing to remember with the D610 and optical flash control. When using the pop-up as a CLS "Commander", any setting other than "--" for the pop-up flash output will almost certainly result in your shutter speed not being permitted to exceed the "Auto FP" sync setting, normally 1/200sec. (At least that's the way my D750 works).

As long as the pop-up is set at "--", the camera will permit any shutter speed up to 1/4000. Your off-camera sb910 and yn-568ex will then be able to use their HSS /Auto FP sync capabilities to light the scene, or add fill as needed...as long as they can see the Commander... and their available power permits it.

All flashes have to be on the same channel to be fired by the on-camera commander. If they are in the same group, they will receive the same exposure adjustment commands. If one is in group A, you can control it independently from the Group B flash which is helpful if one is the main light and the other is the fill or hair light. All must be in line of sight from the camera. However, I have found that the reflections off a white ceiling or background will trigger one if it is behind the subject.

Thanks to a previous topic which I was able to get help I am in need again

I have a Nikon D610 with a Nikon Flash SB-910 and also a Yungnuo YN-568EX (just received the Yongnuo today) On my d610 I have Commander Mode on. Nikon Flash Channel 1 Group A TTL For the Yongnuo I also have Group A Channel 1 TTL
First off should they both be on Group A or should one be group B

I had them both on Group A and it worked a couple of times. Although both are not always flashing. So what am I doing wrong? I appreciate all the help I can get.

If you can put one in A and one in B... (and use the on camera flash as either control only or participating in the flash, it will give you greater control over each flash. Remember that the on camera flash will ALWAYS fire even if it is just being used as a trigger. The onboard flash OR the flash in the Hot Shoe, will always flash during the shoot but if it is set as control only, then it is just sending instructions to the off board flashes and not participating in the exposure. This is a common panic for people just getting started in Commander Mode.

For some reason either one or sometimes both flashes are going off. It seems most of the time neither one is going off. Both flashes are in sight line of the camera. On both flashes they are blinking red, I am assuming they are ready to fire. Something must be wrong.

Are the little IR sensors facing the commander. I don't know where they are located on your flashes but sometimes you have to swivel the head to allow the IR sensor to face the commander.

verify that the IR sensors (a little red circle on the flash body often on the battery side of the flash) is always pointing at the flash on the camera. Also make sure that the camera's built-in flash is UP (if you are using it instead of one of the others as your "Commander". This is the reason that the Nikon flashes rotate on the body (so that the sensor can be pointed at the camera and the flash pointed at the target. NOTE: if you are using one of the other flashes as your control, MAKE SURE that it is on the hot shoe of the camera (or connected to the hot shoe with the appropriate hotshoe to strobe cable (available at Nikon or Nikon supplier for a fee)). Also, if one of the external strobes is being used as commander, make sure it is set to commander on the controls on the back of the strobe.

The sensors are in alignment with the camera. I have the Nikon Flash on channel 1 and Group A and the Yongnuo Flash on channel 1 and Group B. (had Yongnuo on Group A previously)

I will have to play around more to see what happens. Thanks for your assistance

Are the flashes recycling (recharging) at the same rate (speed/time)?

It may seem like a silly question, but I use YN460s that recycle at about 5 seconds at full power. My friend sold me a number of his YN460s at a bargain. I couldn't figure out why my new flashes weren't firing all the time. It turns out he sold me an older version of the YN460 which takes about 15 seconds to recharge. My work around was simple, I put two of them together, made them my fill light, and shot them at 1/4 power. I wouldn't have been able to do that if I didn't time the recycle times of my new (but older model) 460s.

If the flashes go into Standby mode they usually will require a second command from the camera. That's why it's sporadic.

The word "should" is incorrect. You can have many flashes on one group if you do not want to control them separately.

What do you mean by a second command? I actually don't think they are in stand by mode that long. Thanks

Coach17, happens with mine all the time. I sometimes have to take a second shot for my flashes to fire. It seems the first shot wakes them up and the second one puts me back in business. That could be what's happening here.
