Ten House is located on Liberty St., spitting distance from the World Trade Center site. They just got two new rigs, and it fell to 10 Truck chauffeur, Aaron Burns, who doubles as the house photog, to shoot a postcard of these brand spanking new machines. A postcard, and maybe a shot to put on the wall, if things worked out. Read the rest of this entry »
Visited the 9/11 Museum on Friday night. Wandering the halls there was powerfully, meaningfully difficult. The images, feelings, and audio recordings that you walk through and among were staggering in their impact, and ricochet like an emotional pinball through your entire being—head, heart and gut.

Another way of involving a bunch of people while teaching lighting is to use a piece of paper as a light source. In the photo world merry go round of light shapers, light tools, light modifiers, bouncers, scrims, Velcro doohickeys, and bendable whatchamacallits, sometimes just a piece of Xerox paper will do. Tape it on the screen of a computer, and bounce your speedlight into it, and you have a simulated computer light source. Embellish the scene with additional sources. Stir in gels. Mix it up with a light fitted with a grid. Link it together and fire the whole shebang with line of sight TTL. Five flashes, fifteen minutes, done deal.
Or, you keep it cool, simple and elegant. One light into the screen/paper, 1/1000th @f2.8, incandescent white balance. The windows in the background do the rest.
Or, you can make your buddy look like a mad computer genius (which he is), as I did with RC Concepcion, below.
However, sometimes you are confronted with almost no usable light in the background, as in the picture way up top of the post, so you break out a few flashes and have some fun. I had a great crowd at the GPP PopUp in Singapore, and we simply decided to involve a bunch of folks, and turn the auditorium into a nonsensical riot of color. First up, of course, was the copy paper white light/main light, Group A, dialed in to a good exposure for my three person research team. I forget the exact setting here, but in the world of TTL, you often have to dial down the power for this key light. I don’t have line of sight from camera POV, but I have found what happens is that if you fire your commander flash with the dome diffuser on, there is often enough radiant light from that initial pulse scattering around to reach the sensor on the light propped up on the keyboard.
Then, you have blackness in the background, which can turn into….any color you want. I put theatrical green gels on two speed lights, and dished them out into the crowd. They are at about 45 degrees back from the computer, and firing hard light towards my research crew up front. They are hand held, so positioning is, well, seat of the pants. But it works, except when the whole audience is laughing so hard the guys holding the lights can’t keep them aimed properly.
The small foreground fillip we worked into this scene was to cast a fourth protagonist off to the side, the evil poacher who is sitting there copying my award winning research team’s formula off their computer screen. To illuminate this gentleman, Cali is holding a speed light attached to a paint pole, and fitted with a warm gel and a grid. I have to isolate this figure with a splash of light, but that splash cannot be a wave of light, as would be produced by, say, an umbrella. It has to be a directed pin prick of flash that hits my corporate spy, and not much else. If you hit the scene with broad, random light, the directed nature, not to mention the color, of the light you have already created gets swallowed up.
Lastly, mostly for giggles, we threw a red gelled speed light into the background. Directly behind the group, firing backwards, it has a limited spill and play. (You can see the arm of the person holding it.) Doesn’t look particularly good.
Hand held, off to the side, it produced this shot, which is what I led this blog with.
Below, is a sketch ( I use that term loosely) of the overall scene.
Generally, when I teach a large group in a seminar setting, I involve the audience in as many ways as I can. They become my photo subjects, all day, for one thing. In other instances, I pass (or throw, if someone looks like a good bet to catch it) a speed light out there so that some luckless soul then becomes a VAL (voice activated light stand).
At the recent GPP event in Dubai, we posed the intrepid Ali, and imagined him as a young auteur director of indie films who was ginning up a reputation in the Middle East and beyond.
First step, as always, is forget about the flash and the light, and compose the picture. Get control of the scene. The obvious thing to do in that auditorium was to use the center aisle, with glow strips set into the steps, as a compositional element. Once the subject is settled into a reasonable place in the frame, the main light is placed, which in this instance is the Lastolite 2×2 EzyBox soft box, white interior style. It is placed up and to camera left, in sort of standard, regulation soft box position. It does hover at the upper edge of my frame, as I want it low enough to scoop light into Ali’s eyes.
Next are the audience held kicker lights, placed to either side and behind my subject at about 45 degrees. These lights are ungelled, and hand held. (Hmmm…last sentence, beginnings of a rap song about speed lights?)
I digress. Those two lights simply rim his face and form, and define him. The corollary benefit, which to me was a happy accident, is that they also rim lit those auditorium chairs behind him, which have a rich blue color. You do have to be careful how those rim lights are aimed and zoomed. If they go too tight, and too forward looking, you lose the chairs, as in the frame below. Their position, angle, and zoom factor all bear experimentation.
Last step was to place our simulated projector behind him, which was another speed light, Group C, fixed up with a blue gel. (No smoke machine handy. Rats!) Remember in TTLville when you have the actual speed light in the frame, it effectively is blasting into the lens, and thus the camera’s brain, and it can easily go kaflooey. (That’s a technical term.) It will report on itself as being a very bright source, and thus power itself way down, most likely to a level where it’s barely discernible. When you have a backlight like this, in a position that is clearly visible to the lens, best to slam that puppy into manual mode immediately, and tell it how to behave from the get go.
When all these pieces are in play, you can then factor them and play with their ratios, relative to your camera settings. In this instance, I chose f1.4, so the background doesn’t get to be too much of a player, and remains just soft context. Here are the final settings. As always, the ambient light level was the driver. I needed the background auditorium to go relatively black, but did want the glow strips on the steps to radiate into the picture. 1/60th @ f1.4 was a good combo for that.
Below are the flash settings as recorded in the metadata.
Group A: TTL, -1.0EV (Camera: 0EV, Speedlight: -1.0EV)
Group B: TTL, -1.0EV (Camera: 0EV, Speedlight: -1.0EV)
Group C: M x 1/128 Device: SB-910
It’s a fun way to teach in that everyone gets involved, and sees the result built one flash at a time. It never becomes a fully finished picture, as you shoot a few frames and move on, but it does open some doors and solve some mysteries, such as how to tackle an extremely large, dark room with a few speed lights. We repeated the experiment at PhotoShop World in Atlanta, in an even bigger, darker cavern of a convention center, with the ebullient, charismatic wedding shooter Jason Groupp as our subject. He was great, and very patient with my bumbling about.
The below are the same basics, really, with the additional kicker of another speed light (why not:-))) with a red gel aimed at the far, far back wall. And instead of seeing the blue backlight, this time it slams into my subject, giving him a bluish rim. (Jason’s hair was perfect for that light!) And the 45 degree rims have warm gels on them. Variations on a theme. Thanks to Jason for jumping in as our subject!
