Final answer:
In film and television production, the technique of alternating close-ups of characters in a conversation is known as reverse shots or reverse-angle shots. This method captures the dialogue and maintains spatial continuity.
Step-by-step explanation:
The technique described in the question is employed in film and television production, where two characters facing each other are shown in alternating close-ups. This method is known as reverse shots or reverse-angle shots. The camera is positioned over the shoulder of one character to capture the close-up of the other, and vice versa, typically from opposite ends of an imaginary line between them.
These shots are a fundamental element of cinematic language, helping to create a conversational rhythm and maintain spatial continuity. It is an engaging way to show a dialogue exchange, capturing the emotions and reactions of both characters in a scene.
