Hi,

I recently bought a RF602 Yongnuo trigger and reciever. I want to trigger both cameras at once to play about with stereo images. But I want to do it in the studio with studio lights...

I tried tonight and had problems, so here's the set-up...can you say what's wrong?

400D - has the Yongnuo trigger on. This is the lead camera, if you like. But with the trigger on the hot shoe, I can't put the lights to the 400D

40D - has the lights in the RF socket. Also has the receiver which has a cable to the trigger socket.

So, theory is, the 400D shutter is depressed, the 400D AND the 40D shutters are activated, the 40 triggers the flash via the RF socket.

Now, all this "worked"...both shutters fired, and the lights fired. but the 40D had a well exposed image, and the 400D had an underexposed image, as if it had "missed" the lights. Now I reckon there must be a delay, with the 400D shutter activating, and closing again before the 40D is triggered along with the lights.
Does the Yongnuo trigger have a delay? Is there any way around this?

I am getting another RF602 receiver soon, so will trigger both the 40D shutter and the lights on the same trigger signal. Would that solve it, do you think? (actually, I will have it so the 400D is the "slave" camera as I am waiting on the relevant cable for that too).

I have no experience with the Yougnuo triggers, but found this review to be quite favorable.

Why not trigger both cameras directly with a Yongnuo receiver in the hot shoe, and then trigger your studio strobes directly with cord plugged into the PC socket in one of your bodies?

Or use a third receiver to trigger a small manual flash facing your studio strobes, and fire your studio strobes via their optical triggers?

Maybe someone who uses these triggers will join in the conversation.

Yes, I posed this question in other places too and this was the general idea. I have a second receiver on it's way and I need to fire the shutters on both at the same time, receiver on each. The only down side to this is that I will have to have the remote trigger in hand, so if at times I want the lead camera to be handheld, I have to also have the trigger...that won't be a problem for the "static" stereo shots though.

Just waiting for the second receiver. :)

Will post when/if I have any success. :)

You will need two transmitters, i played with this on a single camera firing both shutter and flash and found that you need two transmitters, one to do shutter and one to do flash, put them on different chanels.
