Two for the price of one
Looking down on a cold, dark and very damp part of the building. Here much fun was had with the cameras and flashes, Marc managed to slip in the sludge and stuff got dripped on if you weren't careful.
Strobist setup info: An SB900 clamped onto a head-height girder behind me, set to full or 1/2 power and zoomed to 105mm. Four gelled SB-26s in the background, at about 1/2 power and pointing at the floor. All triggered from the camera by Skyports.
