Great discussion here gents.
Judging by some of the reflections in the glasses I think that maybe it could be from a powerful source with a large diffuser, like a 2×2 or 4×4 frame holding some white diffusion. Perhaps the BG could be receiving a bit of this light and is then softly lit per each situation.
I would love to hear your opinions,
