What is the role of long shots in documentaries?

Long shots are relative to montages, and different directors have different views and understandings. Bazin called it a depth-of-field lens, because it takes a lot of depth of field to shoot different spaces continuously with one lens. Some people think that a long shot is a long shot. The characteristics of a long shot are: 1, which can show the real process of the event and has strong authenticity. (Without editing) It can't deceive people like a montage. 2. A shot can show fuzziness or uncertainty; 3, mostly in the form of sports photography; 4. It is not easy to use, which leads to procrastination and lack of conciseness. 5. A shot takes a long time (there is no time limit).

Long lens and long focal length lens are two completely different concepts.
