You're behind the chair.

在椅子的后面放置了两部调整好的摄像机，其高度保持着与志愿者眼睛的高度一致。

Behind the chair there were two video cameras adjusted so that they were at the level of the volunteer's eyes.

我将2只大力夹夹在了2个椅子的后面，并且在夹子上安装了SB-80DX，直射背景墙。

I mounted the two Spring Grip Clamps on to the seat backs of two chairs. In the clips I mounted Nikon Speedlight SB-80DX and directed them against the white wall.
