Please note the dome in the heading photograph. This is not the targeting guidance system for an Atlas E missile - though they are nice as well. It is a Gary Fong Lightsphere - in this case one of the collapsible ones. Beside it is a packet of gel filters made by Honl. They are the absolute bullet for event and wedding photographers.
Those of you who reel back in horror at the thought of a flash at a wedding - like M. Cartier-Bresson - are welcome to move further down the car. By all means ramp your ISO up and clap a 2.8 zoom to the front of your DSLR and hover over there in the shadows. I'm sure your photographs will be all the better for your artistic decision. I should de-saturate a few of them and tilt a horizon to provide variety. Remember to browse the salad bar at the reception...
I shall be running around in the meantime popping up out of prepared positions to ambush the bride with my camera and the flash attached. That'll be me down there at the front of the aisle as they exchange vows - look for the balding head and the occasional electrical discharge. Note that I will have the Fong Lightsphere firmly attached ( and it does attach firmly ) to my DSLR and a short zoom on the front. And I will be elbowing interlopers out of the way.
If the wedding is to be held in the warmth of a tungsten-lit church I will push one of the amber Honl filter gels down the throat of the Lightsphere to match the prevailing light. Likewise I will push in a slightly weaker amber if I am filling an outdoor shoot in the last hour of the day. My flash will be about the same as the sun then and the subsequent computer work will be so much easier.
If, horror of horrors, the wedding is in a filling station lit only by flickering fluorescent bulbs and the demonic eyes of the guests, I will substitute one of the green filters. Don't laugh - I once covered a wedding where the groom chased the bride through a burial ground with an axe. Nice colours. Nice axe.
The Lightsphere softens and spreads the flash so that there is s pretty good agreement between the illumination on the main subject and the stuff that filters through to the background. Of course you can force the flash to put out more or less light with the controls on the back - all flashes can do this to some extent - and you can force the light to spot the subject by your choice of positioning and distance, but generally you can set a ratio and then just chase the bride at will.
The amazing part of it is that even if you think that your flashes are disruptive, it is unlikely the happy couple will notice. I spoke with the bride from two weeks ago and she did not realise I was working as much as I was until she saw the video from another guest. Thats under the radar. Mind you, if I wanted to promote the brand I would have to have a sign on the back of my shirt advertising the studio to the wedding guests.
