Multiple Flash Triggers – Tech Thursday

Flash Photography

The holiday rush for shopping is almost here, so camera manufacturers are getting into the fray with lots of new products. I am happy with my current setup for most events, but there has been some occasion where having more options for triggering multiples flashes would have come in handy. Working with some other photographers on their projects started me thinking on how I can accomplish this with my existing equipment. They have their own systems, but since I have different gear, I needed to do some thinking.

The monolights I use in my event photography are Elinchrom Style RX 600s which are triggered by the Elinchrom Skyport remote. These fit into the hot shoe connection on your camera. I wanted to have the ability to trigger a speedlight at the same time that the monolight is fired. Althought I could set the speedlight go off the optical slave, it will fire anytime that another flash is fired. In most events now, many have a camera. That would burn the batteries too quickly if this happens. Also it would probably ruin everyone else’s photos that will trigger my flash. Here is my slick solution, that I will try at the next opportunity:

Flash Triggers

Directly connected to the camera is a PocketWizard MiniTT1 for Nikon. Also connected to the hotshoe connection on top of the MiniTT1 is the Elinchrom Skyport. The MiniTT1 is designed to send a radio signal to an off camera flash that is connected to a FlexTT5, and pass the shutter signal through it’s hot shoe on top. Usually another speedlight is connected on that top hot shoe, but I connected the Elichrom Skyport and experimented to see if both flashes would fire. Here are the results:

Having both connected, but leaving the monolight off, the PocketWizard will still fire the Speedlight connected to the FlexTT5.

The Skyport will also get the signal leaving the TT1 on the camera on! I had the Speedlight on a different channel just to see if it would pass the signal while not making a connection to another unit. When I had the MiniTT1 off, it did not pass the signal to the Skyport. So I tried it with both of them on:

Success! I tried this on all available channels, and everything seemed to work. It was just in my basement, so I don’t know the range of this setup, or how it will work over a long shoot, but the early tests show promise. Once I try this in a more demanding application, I’ll post the results here. Let me know if you have tried something similar, and if you have run into any trouble with this setup.

Fill Flash – Tech Thursday

Another dancing couple reached out to have some photos taken. They had decided to try the Georgetown Waterfront to make some nice dance portraits. Sharon and Michael chose this spot as there were some fountains and views of the Kennedy Center in Washington, DC. This spot is right across the Potomac River from Roosevelt Island that we visited recently on a photo walk.

We met in the late morning, early afternoon for our session. That was the best time that we could coordinate schedules. However, this is not the most ideal time for photos. I had to use a lot of fill flash to get the photos we were looking to make. Fill flash is available on any camera today to help balance the bright background from the sun and sky, and the subject that is in the foreground. If you did not have this added light, your photos will have your subjects in silhouette, with a perfectly exposed background. Unfortunately this is typically not the important part of the photo. In this case, you would exposed the fountains, sky, and buildings in the background, and the dancers would be in shadow.

Fill flash is not anything special. It can be the internal flash built into your camera or smartphone, an external speedlight, or a large strobe flash. Adjust the flash to balance the exposure on your subject to match your background. In this case, I had to use 2 Nikon speedlights at full power to get the dancers exposed well in the harsh light. A nice bonus if you get to this point, you get a nice saturated blue in the sky instead of a blown out white sky.

Zoom Your Flash! – Tech Thursday

Of course you can zoom your lenses, but did you know you can zoom your speedlight flash? Depending on the model that you have, your flash head can be moved internally. On the Nikon SB-910, the flash head can be zoomed from 24mm to 200mm – a much larger range than their previous model, the SB-800 which had a range of 24mm to 105mm.

Speedlight Features

If you have this flash connected to modern Nikon cameras, the flash and the camera will talk to each other. They will automatically set the zoom of the flash to match the focal length of the lens that you are using by default. This is a great feature! As you use a longer focal length, the flash head will automatically zoom so that more flash power is given where you need it. Here are some example photos showing the difference in the light produced by the flash at different zoom lengths:

This first photo has the flash zoomed out to 24mm. It is giving it’s largest spread of light against the wall. If you need to cover more area with the flash, this is will cover a wider area. This also corresponds to a wider area seen by a camera lens set at 24mm.

At 70mm, the light beam becomes more focused. There is not as much spread of light up and down from the flash. The more you zoom in with your lens, the less that you need the light to be spread out across the frame, so this only flashes what you need without worrying about the areas that are not going to be seen in camera.

Zooming Flash

The tight beam of light that comes from the flash at 200mm is the most extreme setting. If you are zoom out this far with your lens, there will be a corresponding small area that you need to iluminate that far from the camera. Having these options for you gives you creative possibilities to focus light. You can manually set the zoom on the flash apart from the focal length of the lens. This works well to create more dramatic portraits just by zooming the light you are already carrying! Try it next time and let me know how it goes.
