Who is the film theorist who raised the long shot theory to the aesthetic level?

Bazin, a French film theorist, put forward a film theory opposite to montage theory according to his "photographic image ontology". Bazin and his supporters claim that the traditional film theory represented by Eisenstein is out of date, and only the long lens theory is the modern film concept. Bazin believes that the temporal and spatial continuity of long shots is an important means to ensure the realism of movies. Montage decomposes the complete space-time and events, which is extremely unreal. The director decomposed the montage, and with his own subjective consciousness, the audience was not allowed to choose, so he advocated canceling the montage. This theory is of positive significance to emphasize the authenticity of film and television works, but it is too extreme to completely cancel montage. The practice of film and television creation proves that montage and long shots are both needed and should complement each other and develop together.
