It's tough to have to suddenly think of pictures that have great lighting. It's kind of like being put on the spot. Remember all those times someone has asked you out of nowhere to name your top ten favorite movies?
So after a good deal of searching (e.g. creative googling), I've come up with the following images:
Yeah, I know, The Road was a cripplingly depressing movie. But the lighting in it, although very minimalist, works amazingly to make every shot feel alone and desolate, even when there's multiple subjects in frame like in this screen capture. Everything looks completely glazed over and uncaring, much like Charlize Theron. Those are some stone cold eyes. Sheesh.
There's something to be said for the strategic use of very even lighting as well, as seen here in A Serious Man. The whole movie deals with Larry Gopnik's whole life becoming molten hot with conflict and consuming him. As such, everything around him begins to look the same. I'm sure the fact that his clothes match the chalkboard behind him above was a total accident though. Surely.
