Using light today.

I shot Victoria Fenner today. But only, you will be glad to know, with a camera.

Let me talk you through that, shall I?

Victoria is an audio expert. She used to run the studio at McMaster University that we shot this in. We decided to shoot her doing her thing – and sound is her thing. So we shot in a studio first:

Camera: I shot her with a Canon 1D Mark IV. The camera was on manual at 100 ISO. I used a 24-70 lens set to around 24mm – meaning around 30 “real” mm.

Light: the camera was equipped with a 580 EXII flash to act as e-TTL “master” to drive three 430EX speedlites:

  1. The “A” flash through an umbrella on camera right, shining into Victoria’s face. An umbrella throws nice soft light, great for faces. (There is a certain irony in the fact that we use the word “umbrella” to name this thing that throws around this nice light. Umbra means shadow!)
  2. One “B” flash with a green Honl Photo gel in the background – I love adding a splash of colour, and green goes very well with purple.
  3. Another “B:” flash, fitted with a Honl Photo 1/4″ grid, as hair/accent light shining toward the camera. You can see it just outside the field of view.
  4. I set an A:B ratio of 4:1 to 8:1.

All this took about ten minutes to set up, and ten minutes to take down.

Then we shot some outdoors. For this, I used two flashes off camera: one into a Honl gold/silver bounce card; the other using a grid, as before. Yes, in bright sunlight you can fire these flashes using light-controlled TTL.

This was a bright day in April around noon. But it does not look like noon light, does it? I shot in Aperture mode, with -2 to -3stops exposure compensation. That darkened the background to give it colour saturation. The flashes took care of the foreground.

A portrait with three speedlites

Here’s a portrait I just shot.

I used the Canon 1D Mark IV with a 580 EX II flash on the camera, used only to drive three 430 EX II flashes using remote e-TTL. This is easier than ever: with the right knowledge and tools it takes mere seconds to arrange.

So here’s how I did it.

I used a 50mm prime lens (meaning 65mm effective focal length) with the camera on manual, 100 ISO, f/5.6 at 1/125th second.

The lights were:

  • One 430 speedlite, the key light, is on camera left one foot away from the subject and is mounted on a cheap light stand. It is equipped with a new Honl Traveller 8 softbox.
  • The second, the accent light, also on a light stand, is one foot behind the subject, is aimed forward at her, and has a Honl 1/4″ grid fitted.
  • The third flash, aimed at the wall, is mounted on its little plastic light stand and has a green Honl gel fitted to its speed strap in order to add a splash of colour to the background.
  • I set an 8:1 A:B ratio to stop the accent lights from becoming too bright (the key light was A). I also used – 1/3 stop Flash Exposure Compensation, since the initial frame showed the face a bit bright.

That setup was:

Simple and effective. And if I say so myself, I think the green gelled background accent was an inspired choice.

Today, with small flashes and modifiers, using TTL, you can do professional studio work in no time.
