Autoethnography is also used in film as a variant of the standard documentary film. It differs from the traditional documentary film, in that its subject is the filmmaker himself or herself. An autoethnography typically relates the life experiences and thoughts, views and beliefs of the filmmaker, and as such it is often considered to be rife with bias and image manipulation. Unlike other documentaries, autoethnographies do not usually make a claim of objectivity. An important text on autoethnography in filmmaking is Catherine Russell's "Experimental Ethnography: The Work of Film in the Age of Video" (Duke UP, 1999).
