"There's a major scene that takes place in the steerage common room in which Rose and Jack go dancing at a party down there. If we had just continued with the usual lighting approach in combination with the white walls, we would have had an almost hospital-like atmosphere. "Once I had seen a rehearsal of what the dancers were going to do in that scene, and the kind of energy they were going to add with their performance, I knew I wanted the impact of the lighting to match what they were doing. So we cut holes in the ceiling and started aiming lights straight down to make these really hot white patches of light that the dancers would pass through. The pools were three to five stops brighter than the key light, so for brief moments in a shot we'd get these explosions of energy as they danced and whirled about." -- Russell Carpenter, ASC
