Triggering two strobes - how to?

p.1 #1 · Triggering two strobes - how to?


A couple years ago I been asked to photograph a guy whose pictures ended onto a top German interior design magazine, the guy later told me that after working with a few other photographers he liked my way of working with him which I guessed had more to do with interaction than technical result; after I got paid for the job I decided to try the strobe light to raise the game and bought a Godox AD200Pro, a parabolic soft box, an umbrella and a trigger but besides a couple tests at home I did never really play with that.

Last summer I got myself the little Godox IT30Pro, I often sped days on an open boat by the sea and with the sun high up I thought I'd use it to add a little bit of light to remove the harsh shadows but, again, I never really got the chance to test it.

I would like to give the stuff a try before the summer (which is my working season) kicks in and wondering how to trigger both the AD200 and the IT30, I thought using the former as key light and the latter to add a little bit of light to the hair of the eventual model, my guess is that they both have to be on the same channel but on a different group to be able to assign different settings to both, is that correct?

Grazie

Figured it out, mistake was to assign a different number on both strobes, now both on same channel with number off and I can set them indipendently off the trigger, seems fun!

I use the X3 trigger and V350 as you describe. I like the idea of the little it30 for centre-jour fill, though, rather than hand holding the V350 and triggering from the X3.

I would also love a leaf shutter...

When using multiple lights, it's best to assign each one to a separate group. They will all still fire at the same time, but you will gain the ability to make separate light level adjustments for each light, and from the transmitter on the camera. Putting them all in one group forces all to follow the same levels, make one adjustment and they all follow.

When you change the AD200 Pro II from one group to another, the LED lights on the sides of the AD200 control panel change color. When you learn the colors, you can see from a distance which light is on which group.

I have the old AD200Pro and the IT30Pro, I assigned the same channel to both and Group A for the AD200Pro and Group B for the IT30Pro and they both fire together, I need a model to try and take some shots with both an umbrella and the parabolic soft box, I don't expect the little IT30 to do much but it might be fun to use it to light hair from behind or a side

For the IT39 Pro as a hair light, you might be better off using it without a modifier. You will likely need all the light that you can get out of it. Remember the Inverse Square Law of light - for each foot of distance between light and subject, the light level drops by 1/2. That means that at 2ft distance you only have 1/4 of the light output. At 3 ft distance you have 1/8 of the light output, etc, and adding an umbrella is going to reduce it by 1/2 of whatever it is as it passes through the umbrella. Keep it positioned just out of the camera view and it should work as a hair light. At 10 ft, you probably won't even see it's effect. Each of these increments is one F-Stop in light measurement, and most white photographic umbrellas have a 1 F-Stop loss in the light level as the light is passing through them. This is why I haven't bothered getting any of these new micro flashes. They are almost not enough light output for good photographs at close distances.

Good luck in your shoot. I had once tried getting my wife to pose for me, but after about 10 minutes she asked "how long is this going to take?" When I replied "about an hour", she got up and left, saying "I have better things to do", and she won't come back.

When I asked what other Pro photographer frinds do when they need someone to pose for them and no one is available, they all told me "Get a Mannequin, we have them". My wife wasn't very happy with me having a woman in my studio to pose for me, even if she was plastic, but I did finally buy one, the cheapest mannequin that I could find on Amazon at $86. She was made by Yaheetech, a Japanese Company, and she is beautiful, and not oriental looking at all. I found hair for her at the Halloween Aisle in Walmart (right time of year), shoes, jewelry, and a dress at the local thrift stores, and now she poses for me whenever I need her to, without ever complaining. She will hold a pose indefinitely too, but she is a little stiff and only a few of her joints move, so I have to make use of her in the few positions that she can do.

Now, the dark side of owning a plastic woman for your photography -
I bought a second very pretty party dress and another wig for her, so I could make her look different once in a while. But then one day when I went into the gear closet for another light, I discovered that my plastic woman was building a wardrobe of her own in my gear closet. Nice stuff too, but how was she doing this? I asked her, but of course I got no reply, so I kept watching to see how this was happening.

I finally found out that my wife and my neighbor's wife were shopping at the thrift shops for my plastic woman. After my wife not being happy to have another woman in the house, she had decided that since I wasn't asking her to pose for me any more, that maybe this plastic woman wasn't so bad to have around after all. So she and her neighbor friend had started buying clothes for my plastic woman and filling my gear closet with them. Once I had found out what was happening, I quickly put a stop to it, but by then over 1/4 of my gear closet was full of nice women's clothes. My mannequin is 5' 8" tall and 34-24-35" with size 6 shoes, so a bit tough to find clothing that fits her well in this town of mostly huge women, but one this size must exist somewhere in town and must have cleaned out her closet and given everything to Goodwill at the right time for my mannequin. I've been looking for this real woman, but so far I haven't seen her in town, and I'm still working on returning some of this excess clothing to the thrift stores. I made my wife promise not to shop for my plastic woman (now named Linda) any more.

I could have bought a male mannequin and all this wouldn't have happened, but I decided that since most of the portraits that I take are of females, that a female mannequin would be a better choice. She is nice to look at, but just basically a 5' 8" Barbie Doll. The right shape, but with no sex features, although she is perfect for helping me set up the studio lights for my portrait shots.

Ciao Charley,

well, a solution for the model would be to use an app, not very fond of those but I think there is plenty of dating apps, if then she also wants to pose for you then so much better...

The IT30Pro would only work as a kicker (that's how I think it's called such a light) and not through an umbrella, I would use the AD200Pro (not the MKII) in a modifier (I own both an Buff umbrella which for the money and the effort to keep it open is a real waste and an almost circular deep soft box which also requires the hands of a blacksmith to open and fold) and the little thing to just add a touch of light on the shadow side, behind or whatever, just to experiment which is the thing I like about photography.

Grazie for your hints and good luck with your model/wife

I appreciate the suggestion, but as I've been happily married for 63 years, I'm not about to frequent dating sites.
