I drive past this building every day and have often wondered how it might work as a background for portraiture. I had a vision of a really contrasty image with nice rimlighting, and had planned to use the setting sun to provide that rimlight from camera right (behind the subject), and to use an SB-800 w/shoot thru umbrella as the key light to camera left.
I talked the munchkins into running over there the other evening after work. Sky was overcast, and a little dim which made for nice diffuse lighting and wide open aperture (shooting with the Nikkor 24-70mm at f/2.8), which in turn gave me a nice shallow depth of field with the kids standing about 6 feet from the wall. But it was lacking the contrast / edginess I had envisioned:



Went back to the same postered wall today at around 5:30 PM…clear blue sky, sun relatively low in the sky, but still quite bright…and with the setting sun at his back, there was the rimlighting I was looking for on Conner’s left arm (camera right).
The image below was shot with the Nikon D2x / Nikkor 24-70 at f/4.5. Keylight was 2 Nikon SB-800 Speedlights in a shoot thru-umbrella about 90 degrees to camera left (just out of frame). Why 2 Speedlights you ask? Because I was shooting in high-speed FP sync mode at 1/320s at f/4.5 (100 ISO) to maintain a fairly large aperture / shallow DOF while shooting in bright sunlight. FP high-speed sync lets you shoot with flash at faster shutter speeds than the “normal” max sync speed of 1/250s, but it really cuts down on the output of your lights. By ganging multiple Speedlights, you can compensate for the loss of light in FP mode, and “overpower” sunlight at large aperture / fast shutter speed. In this case, both Speedlights were at full (1/1) power.
Even though f/4.5 is a fairly large aperture, because Conner was right up against the wall, the resultant shallow depth of field is not as apparent as in the images above where he was about 6 feet from the background.

Here’s the DIY “gang flash” bracket I made from a strip of aluminum and 3 cold flash shoes.

And in use either in reflective or shoot-thru mode with an umbrella, triggered remotely with the Nikon SU-800, or PocketWizards:
