Which abbreviation refers to an "extreme close up" shot?

The abbreviation that refers to an "extreme close up" shot is indeed ECU. An extreme close up is a type of shot that frames just a small detail of the subject, allowing the viewer to see intricate features or expressions that might otherwise go unnoticed in a standard close up. This technique is often used to convey deep emotional intensity or to highlight important elements within a scene.

The usage of the abbreviation ECU helps filmmakers and crew members communicate quickly and efficiently during production. It specifies a particular framing technique and ensures that everyone understands the desired focus of the shot.

In contrast, CU stands for close up, which typically frames a subject's face or an object more broadly than an extreme close up. MS stands for medium shot, where the subject is viewed from the waist up or a similar framing that offers more environmental context. ELS refers to an extreme long shot, which captures a broad area, showing the subject far away within its surroundings. Each of these terms plays a distinct role in visual storytelling, making the precise terminology crucial for effective communication in film production.
