How Keith Robins Photography takes portraits outdoors in the dark!
You'd be forgiven for thinking these portraits were taken in a studio - whereas actually they were amid the bluebells of Sparkford woods around dusk, plus another two hours beyond.

Here's Bob, one of YPG's newer members, studying the results of his experimenting with a fibre optic ring flash while the main studio light is set off via my radio trigger. Okay, so I should have made more of the gorgeous bluebells, but I've been there, done that. Besides, portraits are my favourite area of photography.




Running a studio light away from any mains electricity is usually extremely expensive. Not anymore! Maplins sell a 1,000 watt inverter for less than £100
This picture of Charlotte was powered by a 12volt car battery, through a maplin invertor and has no trouble powering a single Elinchrom 200watt D-Lite2.
A Kenro five-in-one reflector helped lighten the shadows and eliminated the need for a second Elinchrom head. The Elinchrom D-lite2 heads have a 4 amp drain but it is only for 0.7 of a second so the 1,000watt inverter doesn't quite reach the stage where the power safety switch cuts out.



Laura, who's never done any sitting in front of a camera before, came along too and with a little verbal encouragement enabled us to capture this lovely semi black and white photo. I said that her eyes were one of her more attractive features and that I'd try to show them at their best.
I love playing around in photoshop and creating these semi black and whites with a softness produced via Guassian blur along with a layer mask.
For instance this one of Laura has a blurred copy layer, but the semi black and white effect is the result of leaving the blur at 50% then highlighting the lower layer and using the Mono button of Colour Mixer in CS2.

I love the way Emily's face is illuminated from a long way around to the left and only creates a small nose shadow in the shot on the left, plus how she's looking straight up at the large white reflective brolly. Shoot-thro brollies seem to lose a lot of power by not reflecting all the light so I'm really glad I snapped up this large bargain of a reflective brolly at a photo sale for £15.
Meanwhile, the nose shadow across Charlotte's cheek doesn't look right here and I should have asked her to tilt her head to the opposite side.
However, I still like the colour, the softness and especially the twinkle in her eye. Notice how the reflector casts a faint catchlight in her left eye?



My favourite shot of the evening is this one of Emily with it's superb soft lighting, a smile that's not over the top, a good sized catchlight in both eyes, plus the way her tumbling hair surrounds her face adding even more beauty to the finished photo.
Bluebells? What bluebells? They were there in the background, promise! I'm more than happy with these results and look forward to the next time with this trio of amazing girls.
Keith Robins.

Keith Robins Photography goes flashing at the seaside! Balancing daylight and flash is not the easiest of challenges, in fact less than five percent of photographers really understand how and why flashguns work in conjunction with available light.
This blog is a mine of information about exactly that.
I'm hoping that by reading all the posts in this blog that you too will be able to handle this most creative of lighting combinations and all you'll have spent is a little time.

Burton Bradstock in early March at around 5pm is the first photo. A flash on that rock in the foreground would have given added interest and help balance the picture.
Second photo is about an hour later. I definitely should have used a flash here - set on minus 2/3rds of a stop so it is not at all obvious - which is surely the whole point of this exercise. Must clean that front filter more often!
It's getting damned cold and my trouser legs are wet through kneeling in the wet shingle with a wide angle lens. Next time I'll bring a pair of wellies, or better still a pair of fisherman's waders.
Brian is seen here struggling with the principles of daylight flash balancing, but he's a fast learner and is soon able to take pictures just like these.

I used F18 at 1/160th on 200 ISO with my canon 550EX on ETTL. Strange to say that the camera, a Canon 5D, was in the manual mode - so too was the lens which is focused on Brian.
Even though the camera is in manual mode it does not effect the ability of the flash to operate successfully in ETTL.
Why manual mode for the camera? I wanted complete control over both aperture to control the flash, plus shutter speed which governs the intensity of the daylight. Now I can make the sky as dark and threatening as I like, mean while retaining a good exposure of my maim subject - usually a figure or a portrait.

This goes against the normal everyday trend of photography where one speed up equals one aperture down to get a similar exposure.
I feel completely at ease with flashguns and this rather unusual way of operating the settings on my camera and flash and have done so for over thirty years. Some of my old manual flashes needed light modifiers such as the lenses from a pair of old Polaroid sunglasses, several layers of handkerchief, or just a thumb placed in front of the flash lens. Nowadays there are auto modes via so many menus it's baffling, plus these modern things seem to have a mind of their own and often refuse to co-operate.
The copyright was added with one click of a brush and then toned down using Opacity.
Hold down the Alt key and type 0169 in the right-hand numerical keys to get a C symbol. type your name - select it with a rectangle - go to Edit, Define Brush Preset, click OK and your logo is the very last brush in the brush palette. Open a new layer before adding your logo, then use Transform to adjust or rotate.

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.
