Some of the backgrounds I worked on for my Degree final film, Banshee.
The painted backgrounds were designed to be projected onto 3D sets. I did the rough layouts for the room and then created it in 3D, then worked on the finished layout and painted background so that it would project correctly onto the objects. We organized a tour of a Georgian historical town house to get some more reference for the kind of furniture and home decor that would match the time period.
