I am going to shoot the following situation:
2 people in the middle of a big room (sitting at a table)
1 person far away from them, kind of in the same room, watching the people at the table from "out of the shadows" (=they can't see this person)
Looking at the room from the "voyeurs" perspective, I can see the two people in the middle of the room. On the right side, there is 2 big windows.
I would like to have a practical or two in the shot. They would be the main light. I'd probably add some fill from the front, too. Then, I'd like to let some blue-green (Roger Deakins style night-time light) light come from outside the windows.
Only problem: The room is too high up, I can't light from outside.
My idea: Install a pole cat / autopole and hang a 1ft 1bank KinoFlo over each of the 2 windows and gel them blue. Blackwrap the endings to avoid spill on the sides and put a louvre on it to shine "forward".
Would that work? / Look good?
I'm a little afraid, there would be too much spill from the Kinoflos being soft. Also: As the windows would be in the wide shot, wouldn't it be a little strange, that the actors and the room are lit blue, but the curtains in front of the window, as the windows itself, are completely black?
The "voyeur" would be lit blue, maybe having only a yellow kicker light.
