how to photograph the movie.

Explanation:

A cinematographer's main role is related to the visual aspects of filming. Editing is usually the editor's job. Questioning an actor's credibility is more of a director or acting coach's task. Casting is typically handled by the casting director. The emotional truth of dialogue is often a writer or director's concern. However, how to photograph the movie (camera angles, lighting, etc.) is directly within the cinematographer's purview.

Answer:

how to photograph the movie.
