Creating a sunny window light in winter

Keith Robins Photography shares a solution to the problem of how to create a suuny aspect to his interior kitchen window cill when it's fairly dismal outside with low cloud cover, it's late in the day and late in the year. This is how his cat, Socks, looks using just daylight.
 So how exactly does he go about this task? Using a flashgun or two of course!
First off is calculating the exposure for what avalable light there is. Selecting a shutter speed of 1/200th to avoid shake, then choose the maximum aperture of F4, after all it is pretty dim out there and detail of the garden wall is required. Well, not really but we'll pretend that it is. 
As the results were way too dark at ISO 200 we decided on 1250 ISO as noise is not too much of an issue with a Canon 70D and Lightroom and the results don't look too bad, but by adding a flashgun we could do better.

   Now to create the sunlight. A flashgun is attached to a tall light stand in the backyard and a CTO (Colour Temperature Orange) filter is placed over the flash lens to warm up the light.
With the flash aimed at the kitchen window to be our pretend sunlight we'll retreat indoors and see how it looks in camera. To bright so we reduce the power setting to 1/2.

  The white balance is left on the flash setting on the camera which creates a very pleasant warm glow.
Adjusting our outdoor flash power to match ISO 1250 at F4 produces the resulting image below and looks a lot more natural, just like a summer's day!
 
However, the rest of our kitchen now seems a little dark compared to the new sunlight coming through the window, so a second flash is aimed at the ceiling well away from the window to make it seem as if the sunlight is strong enough to bounce around the room, which it would do in reality. We now need to find the cat again who by this time is settling into his basket and by pointing out the birds sat on the garden wall Socks is quite happy pose for another portrait.
A rather pleasing shot of 'Socks' peering through a kitchen window results from a bit of planning and a few items which most serious photographers have in their kit bag.

Both flashguns are operating on iShoot radio triggers from China at £55 for three triggers and a transmitter. A setting of 1/128th power is all that is required for the indoor flash and 1/2 power for the outside one. The signal for these radio trigger will bounce around a room in every direction and rarely cause a misfire. but outdoors they only work line of sight up to 50 metres easily. The outdoor trigger is hidden by the flashgun body so a small piece of silver foil is attached to bounce the radio signal at the trigger.

For those who have two sets of radio triggers ti's possible to join a receiver and transmitter together and place this combination in a position where it's visible from both camera and hidden trigger.
 Alternatively, a Yognou flashgun would be an option as they have an optical triggering system built-in, but again it has to be line of sight and a third flash on a radio trigger might be required to fire the outside flash.

All in all a very rewarding thirty minutes playing with flash.

Wow, what has Blogger done to their site since I was last on the scene? It's a work of art now to get up the 'New post' box.
Been so busy doing plumbing and building repairs , yet strangely I've also managed to squeeze in even more photography than ever before with around 4 to 8 photo shoots per week. Most of these have been portrait on location shoots in the woods, by the sea, on hill tops and up to my knees in rivers, plus several portrait sessions in the sea with waves lapping at my pockets. My flashguns and stands have always been with me as my passion for great lighting knows no bounds, even in the surf.

Tonii at WestBay obviously used no flash at all but this is one of the extremely rare moments when I used pure natural light.
Exposing for the brightest part of the sky involves noting the auto exposure settings and then closing down two stops as a starting point. Usually I leave the white balance set to 'Flash' as I prefer the warmer tones. Same too with night photography when I want the tungsten street lights to resemble tugnsten street lights.



Now let's have a look at Tonii in this dis-used wartime building with its gorgeous grafitti. Taken with two flashes, one front and back, with Tonii sandwiched between. I call this sandwich lighting for good reason, preferably with a softbox on the nearest flash while the far light has no modifier and is often wearing a DIY grid.
I quite liked the effect of flare from the rim light and decided to stick with it for the rest of this part of the shoot.



Two softboxes help blend the warm daylight into this image with almost no visible cut off point between the two light sources.
Tonii is so patient and is helpful beyond measure, Although she is never backward in saying if she doesn't like a particular shot, which gets deleted there and then.
So yes, I do show my models / helpers the images as they gradually develope into the finshed product.
The church is run byMichael, a good friend of mine, who says we can borrow it any time he's not using it. Must remember to give him a copy of some of the better images.

 In this shot of Danii leaping over a log in a local forest I wanted to keep the daylight as a blur, plus create a blur behind her. The choices are either go with a stanionary camera on a tripod and catch the blur of white material streaming out behind Danii and freeze her with second curtain flash. Or, I pan with her and get streaky daylight.
After a couple shots of each category an idea sprang to mind - what if I could manage both trains of thought in one shot. By arranging for Danii to be running towards the darker area and panning with her I could turn the camera faster, in the same direction, after the flash had gone off in first curtain sync. I hasten to add that I was using about 1/10 of a second. Also, by the third image, I realise that although I'm turning the camera faster I'm panning it a little too fast. Because the flash is the main illumination here then Danii is less likely to record against the blackness. Her front foot is moving fast enough not to record as a great deal of blur due to the flash, although I did have to go into Photoshop and take out a small amount of blur in that area.

Latest news from Keith Robins

It's been ages since my last blog post here but Keith Robins Photography is still around and busier than ever. For instance, I recently surprised myself and managed ten on-location portait photoshoots in eight days besides working a fifty hour week in my plumbing business.
Now I've turned 67 it should be time to relax and put my feet up. But, as luck would have it, my long term hobby is photographing young ladies so I've brushed the dust off my camera, charged up a few batteries and taken a few on-location photo trips into the countrtside. River shoots seem to feature quite highly in the requests from young feminine beauties closely followed by 'on-the-rocks' at the seaside. If this is what retirement is all about - bring it on!



  I'm not sure how or why but Facebook was kind enough to give me a private page plus a business page, which I don't mind at all as it gives me a couple of options when I upload the results from these exciting photo sessions. Okay, so Facebook resizes all the images for me automatically, which helps make them less desirable to rip-off merchants, plus there is plenty of space for loads and loads of albums. This in turn has attracted quite a few viewers and resulted in new models contacting me ref photoshoots.


    I normally work on a TFCD basis which means I give some of my time and skill, the model gives her time and good looks. The model gets a set of CD images and we both end up improving our portfolios.
    Now, this might sound as if I'm losing out on a load of cash. But actually it's the very opposite - I'm saving myself money! What's happening is that I am now meeting some really attractive models, my persona and techniques have changed for the better. Plus, I consider myself a much better photographer and my skills level has shot through the roof.




   I'm now in a position where I could start charging for my skills because I can physically prove that I'm the photographer who is capable of producing stunning results.  Similar in a way, I suppose, to a brilliant violinist going on the X factor and winning and all his neighbours saying, 'Well I didn't know he could play like that!'
You have to show what you can do, how good you are and only then will Joe Public beat a path to your door. I look on Facebook as being my shop window, plus they even tell friends of friends how good you are - and it's all free!!!!
     I'm gradually putting a two or three results from each of my most recent photography shoots, along with a write-up, on to my Facebook page at:-   www.facebook.com/keithrobinsphotography
I also run a blog based website at:- http://www.keithrobinsphotography.co.uk
    Meanwhile, seeing as I'm now drawing a pension and my customers won't let me retire in peace, what's the point in charging loads of money and then paying income tax on all of it? Or am I sonehow missing the point?

Just been on a 'Subtraction of Light' course with Mark Cleghorn of PhotoTraining4U fame in Cardiff.
Seems like the addition of flash is not quite as necessary as I'd previously thought.
In fact, during the five day course we were starting at 6am and photographing with extended exposures of up to two minutes. On a pier in low lying mist by 10am and then later we went under the pier to discover the equivalent of studio lighting!
Mark's 'Subtraction of Light' course has changed my whole outlook on how I take portraits with the purchase of a Canon 85mm F1.8 lens. I've also begun using the 'Picture Style' modes on my Canon 5D with black and white plus a red filter being my favourite.
Candid photography has never been one of my favourite pastimes, but it is growing on me. Street portraits however, turned ot to be far more rewarding than anything I've previouly tackled with many new contacts each time I take to the streets.
Portraits in the woods now makes me look for 'window light' and a reflector is higher on my list of accessories than a tripod ever was.
But don't worry I'm going to forgo the benefits of using a flashgun.
I'll try to keep you posted on a more regular basis with plenty of results form my YeoPhotoGroup course which now takes place on a Tuesday evening. This is a free range group with no charges, no officialdom and no real rules apart from the basis of, 'We all help each other to enjoy our photography and don't give any negative comments'.
We now have a facebook area and regularly post results, ideas, and hints.
Keith.

Miniscule portrait studio at 1.5 m by 1 metre!
A narrow shop doorway, model four feet away and a single off-camera flashgun bounced off a four inch wide doorframe is all Keith Robins Photography needs to create a superb portrait.
Okay so there is a bit of help from the sun which illuminates Lola's left cheek via the white wall outside. For some of these photos I use my Canon 580 EX with the head reversed and bouncing it off a white tee shirt to my left. The flash is set on ETTL while the camera stays on manual, enabling me to control the daylight to a precise exposure.
Getting Lola to look towards the somewhat darker shop interior helps to open up her eyes and as we all know, it's the eyes that can make or break a good portrait.

I came across Lola a week ago via 'Model Mayhem', a sort of online modeling agency where you sign up, wait for approval and eventually if they think you're good enough you can send out friend requests followed by email contacts with the models where MM act as intermediaries, a sort of buffer zone.
Lola is a newbie to the site as a model but I've had nearly forty years behind my camera as a portrait photographer and i've decided that her portfolio needs a boost, come to think of it so does mine! Besides, not only do I need the practice but, I can't remember ever having photographed a girl with such beautiful red hair or such incredible blue eyes. Mostly, though, I could see the possibilities of some amazing photos with Lola and on this count I think I am definitely about to be proved correct.



We arrange to meet at a carpark in Glastonbury on May 1st and blow me most of the roads are closed due to a series of bank holiday fun runs, the carpark is full but I somehow manage to squeeze in. Lola's mum has come along to help hold one of the flashguns as I can only carry one lighting stand along with all the other stuff us photographers consider important - so why do we never use it all?
I often carry two large bags and pull a kitchen waste bin on a shopping trolley full of lighting stands, brollies, reflectors and tripod, but this time it is just a bagful of four flashes, stand adaptors and triggers.


'Proper Job' supermarket carpark provides a small area of shade under a tree set in the pavement which I use to keep the brilliant sun off Lola's gorgeous red hair - I wanted to create my own strobist lighting arrangements, my own sunlight if you like.
One stand, a Vivitar 285 into a small brolly, a second 285 is held by mum replicated the sun to great effect. Both guns are firing via cheapo radio triggers from China at £60 for a set of three recievers and one transmitter. The benefits are that Lola's blue eyes opened up as she looked into the shade. What appears to be sunlight shining on Lola's cheek is really a Vivitar at 1/2 power, but without a modifier it resembles direct sunlight. The second 285 is bouncing into the small brolly also set to 1/2 power, but due to it bouncing into a brolly this is reduced to around 1/4 power and the biggest benefit is that it's really soft due to the close proximity - about three feet.
You wouldn't think that a carpark would make any sort of decent backdrop but it does. Not having access to a studio should not put you off taking beautiful portraits like these, it is possible almost anywhere to create a work of art using flag lights. Strobism rules!
Then we move on to a narrow shop doorway where Lola faces into the fairly dark interior with a weedy backyard and a whole mess of rainwater pipes in the background lit by sunlight.
Okay, so I didn't stay true strobist with the Vivtars for this part of the photoshoot as I want to push my understanding of the capabilities of Canon ETTL and whether I can still influence this modern automatic lighting technology, or, does it take over and mess up everything creative. To which the answer is - without my strobist knowledge of how to juggle exposure controls these photos of Lola will suffer big time.
Canon's interactive ETTL with more than one flash is now moving further down the list of things to absorb my precious time!
During the two hour shoot I take 115 photos, (eighty-five after editing), which Lola will get on a CD to go on her Facebook page, also on to her MM portfolio. I'm only too pleased to help this delightful young lady on her way as a model who is a joy to work with.
Will I use Model Mayhem again? Yes, without a doubt! Although it's a rather long winded method of contacting suitable models but it's for their protection and I can see why it has to be this way.
Will I be photographing Lola again? Yes, most definitely, can't wait!!!!

Popstar and strobist, Keith Robins Photography, in the bluebells!
This late evening popstar photoshoot required three flashguns, nothing technical though as time was short.
We were also short of an actual popstar so Trevor leaped in with a borrowed guitar.
Photo one gives an idea of the location and the little Vivitar 285HE of which I used two. These run on 6 volt motorcycle batteries as they are allergic to rechargable AA's. Third gun was a Miranda from Ebay at £2 which does run on rechargables. I've got two of these lovely little Miranda's and use them a lot.

All the lighting stands, camera kit and other parphinalia we strobists think we really need, but hardly ever use, is carried in a kitchen waste bin fixed to a collapsible trolle with gaffer tape and bungee straps and is seen here standing in for Trevor while he puts on one of my old movie making wigs.

The trolley wheels folded up on the last photo trip and the weighty kit had to be carried back to the van. The buggy has since been adapted with a solid bar axle for just £2, but at only £12 from Maplins for the trolley I still ended up with a bargain.
I wanted our lively popstar to leap in the air and look as if he's bellowing a few lyrics - He's a few years younger than myself so his knees can take the strain. A tip for those with spare cash and the means to transport it - how about a three foot diameter trampoline from Ebay for twenty quid?
Mounting the flashes onto a Bowens stand, an Elinchrom and an Interfit stand, (Yes I like variety), requires the use of hotshoe to lighting stand adaptors at £6 each off the internet. As nothing we strobists use ever seems to be compatible I've Araldited a DIY metal hotshoe foot on top of each of my flashguns, including my two Canon 580 EXlls, which has the bonus of bringing the flash window right next to a brolly shaft.
But then the breeze catches one of the brollies and a few swear words spring to mind. I now carry a tube of superglue and a few spare brollies.
By keeping one flash in shot the illusion of an outdoor stage venue was a last minute addition which we both liked, then decided that adding a CTO filter made it resemble the sun setting through the backdrop of trees, which we liked even more.


To retain the daylight level, which revealed detail in the bluebells, I used ISO 400 and a shutter speed of 1/80th. I did try 1/20th at F8 but the resulting blur was too distracting plus it darkened the flash too much.

Remember, shutter speeds control daylight and apertures control flash strength - higher shutter speed makes the sky/background darker and lower makes it lighter. ISO changes effect both flash strength and daylight levels so I usually leave the sensitivity set on 100 ISO.
Although the aperture effects both ambient and flash it is primarily the flash strength which is controlled via the F numbers - higher F number darker flash. Of course you could always move the flashgun further away to decrease the strength, or turn down the power setting.
I'm not going to go into how to use highspeed shutter sync right now as cameras and flashes vary so much. Best to study the techniques of this along with multiple dedicated flashes in your flashgun instruction book.
Of particular interest is the Nikon CLS (controlled lighting system), or the Canon equivalent. I've used multiple hotshoe flashguns for thirty five years and find the process simple, straight forward and easy - but these dedicated lighting systems are something else! Bear with me though and when I have sussed out how to use it successfully I'll pass the info on in this blog.

Meanwhile, an aperture of F5.6 returned the best images making full use of the three flashes, of which the Vivitars were set to 1/16th power at six feet front and back and the Miranda on full power at around twenty feet. Keeping all the flashes in sync was an IShoot radio transmitter on the camera sending radio signals to a set of three IShoot receivers on the three flashguns.

I bought this set of Ishoot triggers and the transmitter for £60 from a fellow photographer who wanted a Nikon fit, but then he found there is only Canon fit available.
I've since used these same triggers with Nikon, Olympus and my Canon cameras with equal success as I'm guessing all the little contacts don't actually do anything. They also work superbly with my Elinchrom studio lights and having four channels is a real boon in a busy studio environment.
Meanwhile Trevor is having a ball, leaping and shouting and I'm loving how these three amazing strobes are working together - absolutely wonderful lighting!

Okay so next time we'll add a few more coloured filters and maybe a smoke machine, maybe even try adding a real sun filtering through the trees along with a studio flash to really challenge the sun's strength, but being an emergency plumber means time is often short.
Thank you Trevor for being a great sport and he says he is available for bookings, but don't ring him - he'll ring you.
