Two years with wireless flash triggers

Transmitter and receiver. The wireless transmitter (left) is shown sitting on a camera  hotshoe. The receiver (right) is attached to a light-stand by a tripod-style screw attachment; a speedlight sits on a hotshoe on the receiver.

We don't do much on equipment on Wonky Horizons, but I'm making an exception here. This is not so much a review, but a commentary about two years experience with a set of inexpensive wireless flash triggers. I have mentioned these in a previous post, so this is by way of a follow up.

My Nikon D300 and D700 both have a pop-up flash that can be used to control an external flash, and send exposure commands to it. This is a great way to make lighting a subject using flash more interesting by moving it away from the camera. This is part of the Nikon creative lighting system (CLS) that allows full automation of flash exposure.

However, soon after I began using it with an SB900 speedlight (usually firing through a shoot-through umbrella), I realised a serious limitation. There is a tiny lag (only milliseconds) between the commander flash going off and the external flash firing. The delay is just long enough to allow the subject to close their eyes. My daughter, for instance, has the most amazing blink reflexes: pretty much every time I tried to use the pop-up flash as a commander she would blink, so every picture came out with closed eyes. I also think it is a bit unpleasant to have a hard small flash go off in front of your eyes during any extended portrait session.

Charlie Brown, Spitfire pilot, with BM597. He and Dave Harvey (below) had flown in from Russia via Poland  to Belgium. He very kindly posed with his aircraft for a quick portrait. I added a little light from the SB900 held by another photographer acting as a voice-activated light stand camera right, triggered by the Yongnuo. The added flash makes all the difference to the picture by lifting Charlie from the shadow of the plane, while not over powering the remaining daylight. Camera and flash set to manual exposure.

I had been thinking about getting a wireless trigger for a while when I came across a video by Gavin Hoey, where he used a Yongnuo trigger. These are extremely inexpensive compared to top of the line Pocket Wizards, but, if they're good enough for Gavin Hoey, they should be good enough for me. I actually had the chance to talk to him briefly about them: he was very enthusiastic about them, and said they had been good value for money for him up to that point. So I ordered a set from Amazon.

The device consists of a transmitter (mine is a Yongnuo RF-600TX) that sits on the hot shoe of your camera, and a receiver/trigger (Yongnuo RF-602RX) that has its own hot shoe that attaches to the flash. There is a tripod screw mount in the base of the receiver, so the flash/receiver combination can be attached to the top of a light stand or into a umbrella/soft box support.

Dave Harvey, Hurricane Pilot.  Same set up as above, but a few minutes later, with the sun setting fast. Again, the SB900 was held camera right by a VALS (thanks, Daniel!)

In operation, they are simplicity itself. Switch on the flash and the trigger, and you're ready to go (the transmitter communicates with the hot shoe and doesn't have an on/off switch). The transmitter takes a CR2 battery, and the receiver one AAA. The set I got from Amazon had the batteries with it.

There's almost nothing more to say – they just work. Of course, the downside is that you lose the CLS control of the flash. That's to say the expensive, smart SB900 becomes a dumb slave flash. Bummer. But actually, in real life, this has been much less of an issue than I had anticipated. Having grown up with manual flash it's really not a big deal as far as I'm concerned for the kind of simple stuff I do. The SB900 has a very straightforward manual output power control: this means that it is very simple to set the power output to match the desired exposure. I usually work with the flash set to somewhere between 1/8-1/2 power to get a reasonable balance between short recycling time on the flash, and adequate control of aperture.

The range of the wireless signal is more than I'll ever need. I've no idea what the maximum range is: I've tried it over about 60 metres, and it worked fine, and that is far more than I've ever used in serious work.

One more thing to mention is that my son took them over for his A level photography work.  He liked them so much that he bought a set for himself to take with him to University. His Flickr stream shows he makes a lot of use of them.

From Peter's A level portfolio. For this one, the subject (who shall be nameless!) was lit camera left, through an umbrella outside in the garden, again triggered by the Yongnuo. Picture by Peter Baines.

After two years, all I can say is so far so good. They've worked first time, every time, up till now (says he, furiously touching wood!). Of course, I don't make very heavy use of them, and if I made my living using flashes, a set of Pocket Wizards would be a no-brainer.  But for me, these have been a great value purchase.

Photoflying in Belgium 2012

Spitfire and Hurricane, air-to-air

About 10 days ago, I returned from Belgium after this year's Photoflying days. My lack of blogging since then is not due to any lack of pictures from that time: I returned with a stupidly large amount (121 GB). I have spent such a long time sorting through the images, and trying to summon up the courage to write something sensible about a fantastic event, that I have rather been intimidated by the process of blogging.

I've edited enough pictures now to set up galleries on Flickr and Pbase.

Caught in the light: Spitfire Vb, flown by Charlie Brown

I was there for the whole of Wednesday 15 to Sunday 19 August. On Wednesday, a number of aircraft arrived including, for me, most importantly the Historic Aircraft Collection's Spitfire and Hurricane, piloted by Charlie Brown and Dave Harvey respectively. They had taken two days to fly back from Moscow via Poland where they had been attending the celebrations for the 100th anniversary of the Russian air force. We had a photo session in the evening with them and some re-enactors, which was great fun. Both pilots were in good form despite having long flights to get to Belgium.

Avenger in evening light

On the Thursday morning we all gathered: about 60 photographers, nearly double the number from last year. The event is clearly getting a worldwide reputation as there were attendees not just from all over Europe but from the US, Japan and South Africa. Flight planning began and to cut a long story short, I was lucky enough to get onto two flights that day. The first one was with the Spitfire and Hurricane, photographing them from the Skyvan. The second flight that evening was again in the Skyvan, photographing a selection of warbirds and historic aircraft, that again included the Spitfire, as well as an Avenger, Jet Provost, Yak-50, T-6 and Osa's Ark, the Sikorsky S-38.

The Friday was taken up with largely ground-based photography, and slowly wilting in the heat. It reached the high 30°s C in the afternoon. The accredited photographers had a spot marked out about halfway down the runway where we could catch takeoffs and landings. But it was a long march (I think around 2 miles) from where the cars were parked, carrying gear (two cameras and lenses, including the 200-400 mm f/4) and as much water as would fit in a bag. Lots of great aircraft came through, so, despite the long round-trip, it was well worth it. A pair of F16s did a few great passes.

That evening, I positioned myself next to the taxiway to catch start-ups and departures for the photoflying, which again yielded rather a large number of pictures. There was a night shoot organised by Daniel Rychcick as well with artificial lights on the parked aircraft: I didn’t stay long as (a) I was exhausted and (b) wanted to get back early the next morning at sunrise to catch the early light.

On the Saturday I was up early (roused by a wretched cockerel that woke me each morning with the first faint hints of dawn) and on the flight line at 5:30 AM to catch the first rays of light on the aircraft. I spent a lot of time concentrating on Spitfire because I had an idea about trying to put together an A/V -- more on that in a future blog.

Janie: Etienne Verhellen at work

At lunchtime it was another flight in the Skyvan. This time with the classical civvies: Bulldog, Janie (the Yak-52 of Etienne Verhellen that I flew with last year), Chipmunk, Stampe SV-4c, and the AT-6A. It was wonderful to have Etienne behind the Skyvan as well: if there's someone who knows how to put on a show for those in the Skyvan it is Etienne. He left miles of smoke trails behind us as we flew, and did a very fast flick roll right up our backside that was great fun. Incidentally, I should mention that Hanno Wesdorp, who flies the T-6, was the hardest working flyer I have ever seen: he was up for all the photo flights, as well as flights intercepting arrivals for photography. Hanno is a wonderful guy, but he must really, seriously like flying to do all he did.

It was also a pleasure to meet Geoff Collins again who was over with his Cub "Alice". Along with several others, I had been badgering him for a flight in her, so late that afternoon I was lucky enough to go up in the back seat with Rod Brown in charge at the front. We went for a 1-1 photo flight with the Scottish Aviation Bulldog. The light was gorgeous, and Marnix Tahon in the Bulldog flew beautifully, giving me plenty of chances for shots both on the front and rear quarters. It is a bit of a challenge though: I really wanted to get the full propeller rotation which means shooting at between 1/60 or 1/80 of a second. But the two aircraft are moving in space relative to each other and the Cub is vibrating and bumping around, so the rate of success is small. However, as McNally says, no pixels die in this, so there's no need to skimp on the number of shots. I got more than enough in the end to satisfy me.

Sunset with vintage formation

Emerging from the Cub, the sunset was coming up, and it was starting to look beautiful. There was a vintage formation of small aircraft circling the field with a photoship in attendance. Rod Brown went up with another photographer to try catch the vintage formation. I stood with Geoff and watched as the Cub gamely gave chase. Meanwhile the sunset was getting better and better and Geoff and I said to each other "Wouldn't it be wonderful if that vintage formation went through the sunset?" And after a few minutes they did. The picture that resulted is one of my favourite sunsets recently.

After all that, it was back for the farewell barbecue which was great, except that it was so hot that I had little appetite. The afternoon had got up to 40°C in the end, and we were all just about dissolving in our own sweat. Zoersel Malle airfield (EBZR) is also placed on a sandy plain so it was a bit like walking through a desert at some points. I was glad to get back to the hotel, shower and get to bed.

The Sunday morning was largely a case of hanging around taking a few pictures but with little specific in mind. Eventually, I left with plenty of time to drive back to the ferry at Dunkirk and I was home by 9 PM.

All in all, an utterly brilliant experience. It was exhausting given the possibilities of shooting from dawn to midnight, and enervating in the heat; not only that, but photoflying is the most expensive passion I can imagine coming across. Nevertheless, photoflying has been one of the great experiences of my life. Flying with the Hurricane and Spitfire has ticked an item off my bucket list.

My thanks go to Eric, Tom, Giel, Peter, Michael, Jesse and the rest of the Aviation Photocrew and their organisation. It was great to meet a large number of people I had seen last year, including Daniel Rychcick, Mark Salter, Andy Martin, Frank Grealish and Sonya Cooley, and Kedar Karmarkar who no doubt will write an excellent and much more comprehensive blog piece than me. Among the pilots it was a privilege to make the acquaintance of Charlie Brown and Dave Harvey, and to meet Etienne Verhellen and Jean-Michel Legrande again. I certainly hope to go back in the future.
