Only levels. On this I pretty much just played around with it and gave it two instances of the effect. I pretty much have a few presets I made that give me a starting point, I have a few warm ones, and some dark cold ones, and then I go from there.
Great work. CC really set the mood. Most of the time "heavy" coloring takes away from the film but this time it was spot on. Also the camera angle was well done because it conveyed that the actor was disoriented.
