What does the term "extreme close-up" refer to?

The term "extreme close-up" refers specifically to a shot that tightly frames a specific detail. This technique is often used in film and photography to emphasize a particular element, such as a person's eyes, a hand gesture, or an object that is crucial to the narrative. By isolating this detail from the surrounding context, an extreme close-up can convey strong emotions or highlight important plot points, drawing the audience's attention directly to it. This adds a layer of intimacy or tension to the scene, making it a powerful storytelling tool. In contrast, the other options describe shots that focus on broader perspectives or entire scenes, which do not align with the intent of an extreme close-up.
