Models made to depict settings for use in the theater are usually more detailed than those made for motion pictures and television. A theatrical model may even have a miniature lighting system built into it so that the effect of lighting changes can be seen. Unless the theather piece is to be seen in the round, the theatrical set model includes the proscenium, or frame that defines the limits of the set the audience will see. As the television or motion picture setting's frame is the camera view, the models for these mediums do not have prosceniums, of course, but present the set as it will look to the camera with the possibility of many different angles.
