I put the pocket wizard on my camera (could use a master flash turned to off). The flash was set directly behind her on a stand. 1/200, F-7, ISO 100. I made sure the tunnel would be completely underexposed since we were shooting after the sun had gone down. This would allow the flash to be the only available light source. I had a medium size reflector in front of me over which I shot. The light from behind then bounced back to illuminate her. I shot some without the flash flare showing but this was definitely my favorite.
