DP Wally Pfister on Moneyball: “If you look out at one of these stadiums during a night game, generally all the lights in the stadium are turned on to create a very even light for the television cameras, the fans, and the home viewing audience.  I wanted there to be a little more mood to it, so I shut off half of the stadium lights,” the cinematographer explains.  “That created more of an edge light.  I did it very judiciously and tried to find a formula where I could make it look a little darker, but still within the reality of what baseball looks like at night.  I like using darkness as a tool for the drama and for the mood.” (via)
