I snapped this picture (click it to get a better look) only moments after a theater usher or manager or other staffer had informed us that we were about to watch a movie that had not yet been released, so any mobile phones must be turned off to avoid the temptation of snapping a pic or video of the top-secret information (can you tell I’ve been reading Cormac McCarthy?).
She didn’t say anything about just plain cameras.
I wasn’t there to scoop the masses and destroy Disney’s hopes of springing its latest animated wonderment on the public. Before the movie began, I was fascinated by the room lighting. From what I could tell, uncolored bulbs shone up from sconces, through two adjacent filters — one blue, one red — mounted several inches above the bulb and pointing opposite directions from one another at an obtuse angle.
The light shooting up the wall was blue or red, depending on the filter color. More interesting to me was the fainter, reflected light. Yellow came back from the blue filter, and green came back from the red.
At the least, it’s an efficient way to add color to the room — four colors from one light source. For me, it’s also a visually pleasing blend of geometry, physics, and art.
