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.

My flashgun suddenly starts bellowing smoke!! I connected a 6 volt motorcycle battery via a 4 foot length of wire and it didn't whine when I turned it on. Now that's funny, it's supposed to make a whining sound - hang on a minute, what's this, smoke? Oh Nooooo!!!
I had shaped two blocks of wood to act as dummy batteries in one of my old flashguns plus one of Trevor's guns - trust me to pick up the wrong one!
I had just soldered the ends on and then connected it up without double checking the polarity - silly!!! Always check, double check and then triple check that the polarity is exactly as it should be before turning on the power.
I took ten screws out of the casing and yanked the electronic innards out thinking this was the end of my Starblitz flash, but could see no signs of burnt circuitry. The smoke? Thankfully it was merely the insulated card at the bottom of the battery compartment getting rather warm due to a dead short. Also there are now two battery springs with hardly any springiness left in them. Luckily it's the two that I don't need.
Oh, and yes I pressed on and connected up, correctly this time and Bob's yer Uncle there's that good old familiar whining sound from the flashgun, a little orange light comes on. Yippee!!
Now to see what this baby can really do. Full power recharges in about three seconds. In the mid auto position this drops to about one second and in the low auto (weakest) I can just keep on hitting the firing button and the flash keeps up, the orange light stays on continuously.
Will I ever go back to normal AA batteries again? I doubt it. It's not a cost thing it's all about speed of recycling. I want a flash that recharges quickly, before the client starts to think that you've finished taking photos and wanders off. There is nothing worse than waiting, waiting, waiting for a flashgun to recharge.
High energy AA's are okay for around the twenty flash mark but then they begin increasing the length of down time, then after forty flashes we're up around the half a minute depending on temperature, battery age, flash power setting, etc.
Total number of flashes per six volt battery charge is up around 500 at full power and over 1,000 at low auto setting on the Starblitz. The Vivitar produces over 400 full power flashes but closer to 2,000 on reduced power setting! Now that's what I call Rocking, Man!
The photos accompanying this article are of my Vivitar 285 HV which I successfully converted last year.
Things to watch out for? Short circuits if you carry one of these six volt batteries in your camera bag, picking up the wrong block of wood, dropping the battery on your foot - Ouch! Hop, hop.
Some of you have asked how I clip this battery onto my belt. Two pieces of old car inner tube, they're like heavy duty elastic bands. One goes twice around the battery top to bottom while the other splips inside near the top, down through my belt and out around the lower half of the battery. So quick, it never jumps off and whacks your foot, plus it will hook over one of the adjusting knobs on a lighting stand. I used to work in a tyre company over forty years ago and I still had an ancient inner tube in the shed, 155X13 from a Ford Cortina I believe. Never throw anything away lads!
