Slave+Master on 430 EXII

oldvultureface wrote in post #16001344
Exactly. The 430, by itself, will not respond to another flash unless that flash has master capability. When in slave mode, the 430 is listening for a coded sequence of light pulses from a master flash to determine what mode and what power setting to use. A single burst from another flash will not trigger it.

430s are for slave only. 580s or 600s can be set to master and will trigger the 430s via IR if the 430 is set to slave.

You have to hold down the zoom button until the screen shows CH (Channel), and Slave, etc. For details, check out Gary Fong video on Youtube below.

So it seems that you need to grasp a better understanding of the 622.

At the most basic level, it is a radio based device. Generally speaking, you will need a transmitter (on camera) and a receiver (at each flash). I've never used them myself, but I each is a transceiver.

You mentioned that the 430EXII is alone... thus it cannot receive the radio frequencies from the 622. The 430EXII can only receive optical signaling. Thus, you will need a second 622 attached to the 430EXII.

that just seems odd cause in the studio I just use one receiver for one studio strobe, and trigger it to flash the other 2-3 studio strobes with no receivers... is it just canon's speedlights I need a receiver for each? (non-masters)

What you are saying is that your studio strobes have an optical slave built in. This is not the case with the 430EXII. As previously stated, the 430EXII is looking for a CODED signal to fire - not just a generic flash of light.

You can test this with an IR remote. Take the remote to your TV for example. Point it at the optical slave of your studio strobe and hit a button on the remote... the strobe will likely fire.

However, if you just want the 430EXII to work as a dumb flash, you could purchase a hotshoe and an optical trigger for it.

This assumes that you aren't using ETTL, which will not work properly due to the pre-flash.

The two strobes are without receivers are being triggered by the one with the receiver via the flash. This is what the 430EX is triggered by. The 580EX uses the flash head to send a signal via a preflash to give the 430 the info it needs just before it fires. If you have strobes set up to fire when they receive a flash signal, then you would be able to trigger your strobes with a 430EX mounted on your camera.

ok, i get it now, but for some reason I don't understand this part sort of... I got the YN622s, one on camera (of course) and one with the 430EXII, and my other flash (alone) YN560, all flashes fine.... is it cause it flashes because its a YN flash product with a YN trigger so it makes it easier for communication to flow from camera to receiver to YN flash?

Its because your YN560 has an optical slave unit. It will fire when it sees and flash. The 430ex does not, it requires a radio trigger and receiver to communicate.

Or an optically coded signal

Or a hotshoe and an optical slave

Yes, but those will not work in conjunction with the 622's.

Understood that the Canon (optical) system is out the window with the 622s, but why wouldn't an optical slave work, if that's what's being used on the studio strobes?

I use my 602s for my studio strobes since i strictly got the 622s for ETTL and HSS functions. So if I buy these

Hotshoe: http://www.flashzebra.​com/products/0128/inde​x.shtml
Optical slave: http://www.flashzebra.​com/products/0127/inde​x.shtml

it wouldn't work with the 622s?

I think the answer is... it depends.

I believe if you are using the 622 with the flash in Manual mode, it should work because the flash is doing a simple fire at X power setting. However, if you are set to ETTL, the flash emits a pre-flash allowing the camera to detect exposure of the flash... the pre-flash will cause whatever is connected to those items to fire at that time, and it won't recycle fast enough to fire again during the exposure.

The preflash would cause them to fire. At least a standard optical slave.

I was assuming manual mode
