Cinematographer Danny Cohen tells the story of the challenges of lighting and shooting the epic musical Les Miserables, which included live singing in every take and multiple cameras to capture each one. He says, "You make a judgment on how far you can just let things happen and create an atmosphere in the room to tell the story. The actors were already under a lot of pressure -- they had the pianist playing in their ear, they had to deliver songs take after take, and I felt it wasn't fair to make absolute demands on how and where they could move. Smart actors can feel the light and know where to go. I wanted to give them the freedom to make it work, and I think having them moving in and out of light and shadows has given it a more period look that works for this dark story."
