Documentary organizations tend to differ from fictional film narratives in two primary ways: they do not use the same temporal logic, and they do not present a presiding focus on how a central character motivates and moves events forward. The three organizational structures of documentaries, as outlined in The Film Experience, are cumulative, contrastive, and developmental. Cumulative organizations present a catalog of images or sounds throughout the course of the film that may not have a recognizable logic connecting the images. Contrastive organizations presents a series of contrasts or oppositions meant to indicate the different points of view on its subject. With developmental organizations, places, objects, individuals, or experiences are presented through a pattern that has a non-narrative logic or structure but still follows a pattern of change or progression.
