Films are an integral part of our cultural zeitgeist, as time goes on, they have become more than entertainment, they have become a mirror that we point at ourselves in order to explore issues and our position in the world. To do this they use a myriad of tools to communicate with us quickly and effectively and from a design perspective this communication is at the very heart of what we do. FilmGrain is designed to visualise the colours of a film in order to explore whether the visual language of colours developed by the director and directory of photography stands up when removed from the context of the visuals. This paper will explain the process by which FilmGrain captures and visualises film colour data.
