A couple of folks were interested in a sketch of the lighting grid for the ballerina and the wall, so here it goes.
Now I was just starting coffee, and the twitch in my pre-dawn fingers hadn’t yet disappeared, so this artwork is less than magnificent. But hopefully you get an idea. The bed sheet is camera right, two SB units behind it. Camera and model are pretty straight up. The gaffer tape gobos I spoke of are on the wall side of the strobes, shielding the wall from spill. Always remember, when you set a flash off, those photons go everywhere. Omni-directional, in other words. They just don’t go in the direction the head is pointing. (Would that they might do that!)
So, you feather the units. There were a couple of questions about that as well. In this case, I feathered the lights by swiveling the left, towards the camera, and almost past the dancer. They are actually aimed at the empty space between the camera and the subject. Pretty radical, but the soft spill created by the bed sheet covers her well, and the feather move lets the light fall off before it hits the wall. Thus the wall is just, you know, there, and I didn’t light it up and hang a sign on it, “Here’s the wall!”
