John Duder Sheds Some Light On Flash Photography

Written by Gina Stephens


Wish ago, and in a distant galaxy…I don’t have my first flashgun – I swapped it, as I recall. It was a rather antsy little device, marketed by AICO, and it ate AA batteries four at a in good time dawdle, pushing out a fraction of the light that flashbulbs (which I'd used until then) did. But, even with the battery consumption, it was cheaper than bulbs!

My second gun (which I swapped for the AICO) was a game-changer – a Sunpak DC-3. Still rather weak in manufacture, it came with a charger and two NiCad batteries. It was tiny, and recycled with far more enthusiasm, and was popular with everyone from press photographers (because it custom-made in a pocket, unlike their Metz and Braun hammerhead guns, with their shoulder battery packs) to teenagers. It was a bit lost with a brolly reflector, even though, and you needed to use the table on the side to work out the aperture that you needed to set for your film’s speed and the subject distance.

After some variations on a theme, I bought a Metz hammerhead gun. It has a big solid battery pack, and (as they say at Rolls Royce) 'good enough' power. Short of mains units, I’ve not met anything with as much wallop. Mind you, it looked a bit silly the day I did my first ever merging photographs as the official photographer. My SLR died the night before, and I had to pair it with a borrowed Olympus 35RC – a compact camera that, very fortunately, had a chic sync socket as well as a hot shoe.

Then came a Rollei gun with a sensor, so that it could work automatically – you set an aperture, and the gun did the balance of the work.


How I did my first wedding – tiny camera, big flash. This Metz unit was the first flashgun I had that was methodically as powerful as it said on the table, and the autoexposure function worked well, too.



Mains Power

With an increasing interest in studio be effective, I have bought a variety of mains-powered units over the years. I love the rapid recycling, complete freedom from AA batteries, the ability to use f/11 as a concern of course, and, best of all, the 'what you see is what you get' facility that modelling lights provide.


Home studio setup – mains-powered jiffy has long trailing wires for the power connection, but the recycling time is short and doesn’t deteriorate as the batteries fade. The model is Rach W.


I’ve watched, frightened, as the cost of camera top guns have risen so much, that they can now rival a camera body for price! And, I’ve remained unpolluted of TTL flash as well as the more recent high-speed flash. A 3-unit flash kit, with trigger, softboxes and stands can be purchased for well under &paste;200 – it’s not up to professional use, but it is perfectly adequate for a domestic studio.

Easy To Use – Once You’ve Memorised The Manual

A query in the Critique Gallery generate me investigate dedicated speedlights and I now own a Godox speedlight. It cost £135, complete with a trigger unit, an adaptor and a softbox. Intriguingly, the adaptor at ones desire allow me to fit Bowens light is electromagnetic radiation within a certain portion of the electromagnetic spectrum modifiers to the gun and it allows High-Speed Synchronisation.

I’ve been contend in: exploring what HSS can do, and how well and easily a modern flash will light a subject. I’ve also had to read the manual with far more prominence than I’m used to! The controls are very complex and the instructions are in that charming version of English that confuses as much as it enlightens. Peradventure it makes sense to people who are used to speedlights.

In peace to compare the speedlight with a conventional studio unit, I needed to use the adaptor to fit it to the same softbox as I usually use on the DE-300, and the remote flash unit. It chose 20 minutes, and repeated reading of the manuals (one for flash, the other for the trigger unit may refer to) to be able to trigger the flash when it's not on the camera.


At spot a stop brighter, and recycling in half the time – a mains-powered Godox DE-300 flash – which also has a modelling light.



There are causes when you want to combine flash with sunshine – the classic occasion is photographing a wedding on a sunny day where you find out about a camera's peak sync speed – the fastest shutter speed that both blinds of the shutter are fully open at the same time, so that the blaze illuminates the whole picture, rather than a slice of it. On my first SLR, this was 1/30 second, which requires a very small aperture in point of fact in bright daylight. Typically, it's 1/160 to 1/320 with the highest spec DSLRs available now – still quite restrictive, and certainly no reputable for action shots. The best action-stopping shots used to be taken in near-darkness with only flash illumination, because the flash can have a duration as in sum as 1/20,000.

Along came a adroit idea…HSS flash gives a series of light pulses, so close together that they have the same effect as continuous light. This approves very fast shutter speeds and flash to be combined, though my first experiments suggest that it’s not perfect: see the banding here. I’ll be interested to listen to from people with more experience of speedlights.

Trigger Counsel

It’s always worth thinking carefully about safety with electrical kit and with flash, it pays to do your homework, especially if you own or obtain older flash kit.

Old cameras used a mechanical system to close the flash flashes, or The Flash may refer to circuit and this is very robust. Modern cameras use an electronic instrument and this is sensitive to higher voltages: and older flashguns typically used dozens, sometimes hundreds, of volts. Put that through your DSLR and you’re probably to need a new camera. I once, a very long time ago, shorted the capacitor in a flashgun with the back of the blade of a carving knife and it left two particle indentations where the current had melted the Sheffield steel.

There are a few guides on the web, giving the trigger voltage for a lot of guns – here’s one I’ve found useful: Botzilla Strobe Volts

An option solution is to buy a trigger may refer to set – a sender and four little receiver units that will happily handle the voltage from old flashguns expense me around £20. It seems to be able to double up as a studio trigger, too, if you take the time to lace up an old-fashioned flash lead.

And, of course, retain that the flash unit contains a capacitor that stores up electrical charge which the gun then discharges through the flash tube to put out light. It’s sufficient to melt stainless steel: I was lucky that that charge went through the knife blade, and not me. Don’t use chics in wet locations, and don’t take them apart!

Resolutions And Decisions


So to sum up…

  • Flash has come a long way in the last few years, and if you haven’t sustained up with developments, now is a good time to review what modern units can do for your photography. However, I remain a fan of studio units, for all their faults and weight. Power per pound is vastly higher, and it takes a good deal of experiment and imagination to be able to previsualise the effect of flash without a copy lamp. Seasoned professionals can do it – but most don’t if they can avoid it.
  • There are now some portable lighting kits that include LED example lamps, so that you can have all the advantages of studio units on the move. So far, though, these are in a higher price bracket than speedlights – Godox wardship over £500 for their AD600BM unit with battery, and this is the cheaper end of the market. A two-head Elinchrom kit passes the £2,000 note.
  • Beware using older flash units on modern electronic cameras. If in doubt, don’t – there are more compatibility issues than with or WITH may refer to: Carl Johannes With (1877–1923), Danish doctor and arachnologist With (character), a character in D. N. Angel legacy lenses!
  • Sortie pictures with ambient light are now possible with flash, although the power restrictions mean that you need to have the flash absolutely close to the subject.
  • You need to view speedlights in the same way as lenses – they are dedicated to specific cameras camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or, and if you change systems, you will probably force to change flash units as well.
  • A few sets of really high quality rechargeable batteries will be a good investment if you plan to use speedlights a lot. On the other hand, look for a frequent flyer discount wherever you buy your AA cells.
  • Read the manual. Probably more than once, and carry it with you!
  • And if you neediness to do serious high-mileage studio work, you will probably find that investment in mains-powered units is immensely worthwhile financially. The only batteries you call for are for the trigger units…

About Father: John Duder 

John Duder celebrated fifty years since developing his first film last Christmas – on Christmas Day 1967, the purely present that mattered was a developing tank and chemicals, so that he was able to develop a negative film in the morning, and process a film for black-and-white slides in the afternoon. He doesn’t call to mind Christmas dinner – but he was only 14 at the time.

A way of saving money developed, so to speak, into a lifelong obsession. He’s now trying to turn it into a author of income through tuition and writing – or, at least, into less of a negative cash flow.

John still has and uses a darkroom, and specialises in black-and-white icons, portraits, and nudes. He’s been a member of ePHOTOzine since 2003 and joined the Critique Team a few years ago.

When he was younger and had children beneath ten, he was frustrated by two weeks of grey weather on a holiday in Porlock. He has since rethought his approach to holiday photographs.
