A film still (sometimes called a publicity still or a production still) is a photograph, taken on or off the set of a movie or television program during production. These photographs are also taken in formal studio settings and venues of opportunity such as film stars' homes, film debut events, and commercial settings. The photos were taken by studio photographers for promotional purposes. Such stills consisted of posed portraits, used for public display or free fan handouts, which are sometimes autographed. They can also consist of posed or candid images taken on the set during production, and may include stars, crew members or directors at work.
The main purpose of such publicity stills is to help studios advertise and promote their new films and stars. Studios therefore send those photos along with press kits and free passes to as many movie-related publications as possible so as to gain free publicity. Such photos were then used by newspapers and magazines, for example, to write stories about the stars or the films themselves. Hence, the studio gains free publicity for its films, while the publication gains free stories for its readers.
