Lighting - effect - equipment

As the atmosphere for our thriller opening will be predominantly dark. The lighting will be low key in the room with the protagonist. If possible, we will want one dim light bulb in the middle of the room above the protagonist so it provides a spotlight on the protagonist as well as dimly lighting the whole room around him. For the flashbacks we will film as it gets dark so it continues with the atmosphere of the credits. If we were to film in the day it would contrast too much with the shots of the man in the room.
