Yeah.Step 1: Be Beyonce.
It looks like they have her choreographed to stay in the light of the projector, rather than stage light. Look around 1:15 where she's a bit too slow and wanders out of the light.
I can assure you the projector (actually a pair of stacked, superimposed projectors, Christie IIRC) was the only light source.
Cameras were white-balanced to the projectors to eliminate any unwanted tints or off-colors.Would plain "white" projection really light her as well as it appears to be doing? Wouldn't she look more blue/grey or washed out? Would it be possible to warm up the light that falls on her without noticeable bleed on the screen? This is obviously a live performance but could some of these effects have been enhanced slightly after the fact? (contrast, color temp, white balance, etc.)
I can't tell; is that a front or rear surface?
Good point. Now that you mention it, this was probably a camera & light ops dream come true. "Nothing to do for 3 minutes? Great, lets go get a hot dog!"It looks like they have her choreographed to stay in the light of the projector, rather than stage light. Look around 1:15 where she's a bit too slow and wanders out of the light.
This also means that since the projector is the only source of light, she'll look flat since everything is straight-on. It's not obvious from the angle the video is shot at, but it'll be noticeable from angles further to the sides. It also means that the projector needs to be REALLY bright.
