Using V6 to trigger Studio flash strobes in sequence for cut-out mask

namgiaonline · June 2016

Hello everybody,

I hope you can help me. I plan to photograph product like this:

-One Flash A behind the object as backgroundlighting . It will be fired only together with 1.st shoot to get the mask

-Two Flash B & C in front of the object as motiv lighting. It will be fired only together with 2nd.shoot

The only problem i see is that, i only have the big flash strobe in studio like walimex, hensel...

How can i use Cactus V6 to trigger them sequencely?

Thanks much

Hello Sadaha,

You can connect the V6 o a studio strobe by using PC sync cable such as this one:

There won't be remote power control, but there's no problem with flash triggering signals.

In fact you could hook up two strobes to Group A and/or B, and another two strobes to Group B and/or C, and it will work just as if connecting portable flash units (speedlights).

I hope the above helps! Thank you.

Hi Antonio,
thanks. It means that i need to buy 3 Cactus V6 right?
- one pluged into flash group A as Rx
- one pluged into flash group B as RX
-one mounted to camera hotshoe as TX

And when i shoot one photo after another, the flash group will sequencely be fired, A on- B off then A off- B on, and again right?
Do i need any setting in camera? i have a canon 70D

I ask too much to make sure what i think is right , because we let the PC remote the camera shooting automatically in sequence

Thanks

Right on, Sadaha!

One V6 (TX) on camera's hot shoe, and each flash gets one V6 (RX) unit.

On the camera you just need to seelct continuous shot and press and hold the shutter button. Here's an example:

Thanks!

Sadaha,

just in case the video is not a 100% clear, for your purpose you can use the V6's group cycling mode.

In your case you would assign your flash "A" to group A, and your flashes "B & C" to groups C & D (or both"B & C" to group C, in case you don't want to or cannot control their power independently).

In the "AB-CD" group cycling mode, the V6 will then alternate back and forth between your flash ensembles "A" and "B&C", i.e., you will get separate exposures for your mask and standard lighting.

@Class A: thank you ! i have worried that in the video the camera was set with "continous shot" while i want to make single shot
Now its clearer. I'll buy 3 cactus v6 later in amazon
. I'll post the result here
