The shooting platform. Directly above Cat and the perspex - D800 on a tripod arm, tethered to my laptop, and firing the flashes via the rather marvellous Air remote - ye gods I love being able to adjust flash powers from up in a gantry like this, rather than having to come down the ladder each time! There's a magic arm clamping the tripod to the gantry, just in case I get over excited, start dancing around, and knock it off. This was shot in a daylight studio, and there's only a thin layer of material between me and the skylight windows up there - it got bloody hot bloody quickly!
