The set decorator keeps a photographic record of the set. As the set stands from day to day, furniture and other objects must remain in the same places so that shots will match and furniture will not appear to jump from one place to another from shot to shot. If a dinner scene, for example, is shot for several days, the set decorator takes Polaroid shots of the table after the last take of the day so that in case someone moves any of the objects on the table, the next day the set decorator can refer to the photographs and correct the table settings to match those of the previous day.
