Today, the documentary film is associated with knowledge, reliability and credibility. This genre standing with the reality is a focal medium of the society for resolving of problems, reviewing of the issue and getting education. What are the essential and audiovisual features which help to the documentary film making to preserve belief of viewers simultaneously with progressing of the up-to-date media trends, not to lose its authentic appearance and advantages for centuries?
