How did she do that? I mean, there is no pulsation or any kind of light-fluctuation in the feed-back. I've also seen Schreiber's setup and a comment that he maintained a constantly illuminated 'cloud' of feedback. Is this supposed to be the stabilization of the loop? Perhaps this is the right configuration for them to build up - somewhere in the middle of this video the person set the picture at an angle that looked very similar to the one in the Schreiber's face-shaping samples. Did she do that by changing the camera's iris? Attached Image (viewed 386 times):
