Back to last night’s game—this is a crucial part of the 3D broadcast process; these are the screens the truck-guys watched to make sure the left-eye and right-eye pictures “came together” (not a technical term) properly. They watched those grey pictures on the left like hawks. Those projections highlighted whether the dual pictures were in registration (my term, maybe theirs too, I dunno) or not. Remember, most of the cameras were right down on the field, and the field was HOT! Tough conditions, we thought…but the guy in charge of the cameras said they’d done 3D shoots in India, Australia, so this was, well, not the worst yet.
