Studio flash outdoors - at night! Okay so maybe it's been done before via an extension lead. However, Keith Robins Photography is adventurous enough to investigate the great outdoors as a backdrop and discovered that full length portraits do not need rolls of expensive background cloth / paper. Nor is there any need to flag any of the flash heads to prevent stray light illuminating those annoying creases which seem to occur in even the smoothest and blackest of background material.

In a few of the recent posts of YeoPhotoGroup, an off-shoot of Keith Robins Photography, you may have noticed us using a generator to power a pair of Elinchrom D-Lite 200's. Handling that heavy beast of a generator took two men to carry it plus two more to carry our camera gear and all the other boxes and bags of lights, stands, reflectors, modifiers, softboxes and assorted cables necessary to operate an outdoor studio.
Eventually, in a rash spur of the moment decision, I splashed out on a caravan inverter plus a new 12 volt 45 amp battery for my works plumbing van meaning there is now a spare battery in fairly good nick going spare. We can now operate two powerful studio lights from a small two wheeled shopping trolley containing this make-shift 230volt power supply.

Elinchroms are renowned for their 0.7 second recycling time which allows you to capture that fleeting expression of relief just moments after the shutter has fired which is when some models appear to briefly relax during the often daunting task of posing for the camera. During this two hour bridal shoot the recycling time for our D-Lite 200's remained very close to manufacturers specs and never went once over two seconds. An additional benefit is that once the really short time the lights take to recycle, the drain on the battery drops to such a minimal amount that it would probably last a whole weekend before the old van battery needs recharging.


In the first image here, Hannah is sat on a plastic sheet to keep her dress clean. A softbox front left and quite close created a soft main light and another Elinchrom with an alloy reflector lit the bushes behind her. Grace joined Hannah for the second and third pictures and revealed the difference our lights made to the texture of their lovely dresses. A silvered sun shield from a car windscreen mounted on a framework of plumbers 15mm copper pipe helped illuminate the shadows on the right. (More details on this DIY gadget in a later post)
Using 1/200th of a second shutter speed caused the background of Sydney Gardens in Yeovil to go black, while f11 at ISO 200 controlled the lights. All this was between 8pm and 9pm on 9th September, hence the lack of available light.
Our next challenge is to get a little more ambient light into the background, probably a seaside sunset along with a striking silhouette.
Then it'll be a portrait session with a firework display going on behind, okay so we could handle either of these tasks in Photoshop but where's the lighting challenge in that? We'll probably revert to our hotshoe flashguns for this one although I am very tempted by the much stronger Elinchroms which can handle a softbox or a large brolly without losing too much light.

Hand held fairground night-time shots are nothing new for Keith Robins Photography, but now we're trying the same technique with the addition of a flash.
Camera settings for these shots are half a second exposure at f5.6, 100 ISO and my motorcycle battery powered Vivitar 285 HV on 1/16th power. I asked Grace to stand about six feet in front of me with the brightly lit fairground ride another twenty feet beyond and hand-held my Canon 400D.
I've visited the Great Dorset Steam Fair on many occasions over the last thirty years but only ever used flash successfully back in the seventies on slide film.
Now, with digital you'll be thinking that things are a lot easier - not so! When you love pushing the boundaries of flash photography nothing is easy, or is it? I practised with a flash plus a small twisting curl of the camera body in the first image, then used the same settings for the remaining images which gave me time for a flash plus zoom (the second image).

For the third image there was plenty of time to wave the camera in a small semi-circle without a flash.
Although I did have a Manfrotto tripod with me I just had to try this little experiment without it. Besides my tripod was being used by another member of my little group who had accidentally left his at home.
On the third image I managed to carry out all three manoeuvres while the shutter was still on half a second.

This final image shows Grace lit by 1/16th powered flash quickly followed by zooming the lens towards the telephoto end and tilting the camera slightly downward. Okay, so it took a few attempts to get the fourth shot but the final result works for me and to hear Grace's gasp of astonishment when she saw it, that was reward enough.
Next challenge for YeoPhotoGroup members is a gritty urban portrait using both my Elichrom D-Lite 200 studio lights on a single 12 volt battery. Yes, of course I've tried this rather extreme approach - it works fine - he said with fingers crossed. Look up a new post in a week or two to see how we get on with what are basically indoor lights in an outdoor environment.

Flash and blur in the same shot! I said it was possible, but we did take over an hour to perfect it. Second curtain flash was already agreed long before we arrived on site, although why my Canon remains fixed in the first curtain mode regardless of menu settings does baffle me.
With a gale blowing like a demon we were on top of Hamhill frantically holding onto my Elinchrome D-Lite 200's. The softboxes nearly blew away, the rainclouds threatened but the wet stuff held back just for us.
We got beeped at by grinning motorists and Nicki received a quiet yet complimentary wolfwhistle. Meanwhile the shots mounted up as we struggled with shutter speed and panning techniques until Kelv's preview screen produced this super picture with the elusive blur.
1/20th of a second at f11 on 200 ISO - Fantastic! I've even framed it in my excitement, plus I have added a little escapism for the front wheel.

Now I wanted just that little bit extra umph. Lifting the D-Lite head off the lighting stand, which was tied to a 'No Waiting' sign to prevent the wind whisking it away, I then mounted it on the end of a decorators extending pole . I managed to hold the light with its dished reflector about six feet above Nicki's head and another six feet in front.

At some twelve feet long the unwieldy pole proved quite a handful, even though the flashhead weighs next to nothing it was over ten feet away from my hand and being whipped about by a gusting wind.
After twenty attempts we managed to finally get a natural looking background blur and becoming frustrated with trying the judge speeds and distances with one second shutter speed in second curtain flash mode
We ended this challenging shoot in damp darkness at around 9pm and were glad of our yellow safety vests which kept the traffic at bay.
I am definitely more than happy with these great results and am now busy planning the next challenge which is a flash lit subject, plus movement of some sort of ambient light or available lights in the background. Maybe the Great Dorset Steam Fair will help shed some suitable lighting. Keith (Strobist) Robins
