I'm working on a short-film in which there's a scene that takes place in poor and slovenly house. There is a broken window from which the daylight comes in and we want to achieve the feeling of cold winter inside the house.
The scene will be shot in day so i will use natural light hitting the window and, depending on the day, I will add soft-light coming in the house from the same window and WB set for daylight.
To create the cold winter look indoor I thought of using kino daylights +CTB from the same wall of the window but then it will be noticeable that there are 2 sources with different WB.
How could I achieve this cold winter look as if it's coming in from the broken window?
