Documentary & Doc Fiction Films:
A documentary film is a non-fictional, motion picture intended to "document reality, primarily for the purposes of instruction, education, or maintaining a historical record".[ Documentary has been described as "a filmmaking practice, a cinematic tradition, and mode of audience reception that is continually evolving and is without clear boundaries".[ Documentary films were originally called actuality films, and were one minute, or less, in length. Over time, documentaries have evolved to be longer in length, and to include more categories; some examples being: educational, observational, and docufiction. Documentaries are meant to be informative works, and are often used within schools, as a resource to teach various principles.
Social media platforms, such as YouTube, have provided an avenue for the growth of the documentary film genre; These platforms have increased the distribution area and ease-of-accessibility; thereby, enhancing the ability to educate a larger volume of viewers, and broadening the reach of persons who receive that information.
Polish writer and filmmaker Bolesław Matuszewski was among those who identified the mode of documentary film. He wrote two of the earliest texts on cinema Une nouvelle source de l'histoire (eng. A New Source of History) and La photographie animée (eng. Animated photography). Both were published in 1898 in French and among the early written works to consider the historical and documentary value of the film. Matuszewski is also among the first filmmakers to propose the creation of a Film Archive to collect and keep safe visual materials.In popular myth, the word "documentary" was coined by Scottish documentary filmmaker John Grierson in his review of Robert Flaherty's film Moana (1926), published in the New York Sun on 8 February 1926, written by "The Moviegoer" (a pen name for Grierson).
Documentary filmmaking can be used as a form of journalism, advocacy, or personal expression.
