"Advanced Wireless Photography. Remote not firing."

Hi

This is the set-up:

SB-910 as master.
SB-600 as remote.

SB-910 set to ---
SB-600 set to either M or TTL (same problem either way)

I was in a subway on an overcast day. Basically the problem was the Sb-600 wasn't firing. The only way I could get it to fire reliably was pointing its light-sensor (which is on one side) directly at the SB-900. Even 2 metres away with the SB-910 pointing in roughly the right direction it wouldn't fire.

Later on in the same shoot I tried again and it worked, every time.

I'm just wondering if the problem might not have been daylight i.e. the wireless communication works better when it is dark. In the daylight it can't distinguish between daylight and the flash pulses?

Or am I way off?

Thanks

Justin,

That is normal behavior. In any situation where there is no bounce of the IR command signals, the Remotes won't see them unless the IR window, that you correctly noted, is on the side, is pointed directly at the commander.

However, it is not hard to point the IR window at the commander. All you have to do point the flash at the subject and swivel the body to point the IR window at the commander.

In addition, it is best to use the diffuser on the Commander and point it straight up, so the signals will go in all directions and hit all the Remote wherever it might be positioned.

Indoors, in a relatively small room, like a studio, the Commander IR signals bounce off walls and ceiling, and they will usually find their way to the IR window on the Remotes no matter which way they are pointed.

Outdoors or in a large room like an auditorium, the Remotes must be pointed at the Commander.

Daylight does reduce the range a bit, but the biggest effect is the lack of bounce for the Commander signals.

Thanks Russ.

It did work better later in the shoot and I was using bounce then. Your other points; e.g using the diffuser are all noted.

Thanks, Russ, for that concise explanation. I'm beginning to appreciate that while Nikon lighting systems are quite complex, the capabilities make it well worth learning.
