What is the primary focus of a Close Up (CU)?

A Close Up (CU) is primarily focused on capturing specific details, often highlighting features such as facial expressions or particular objects of interest. This shot is vital for conveying emotion and establishing an intimate connection between the audience and the subject. By concentrating on critical aspects like the eyes or a significant object, a Close Up provides clarity and depth, immersing the viewer in the moment and enhancing narrative engagement.

While the other choices suggest various framing options—such as feet up, waist up, or shoulders up—these typically correspond to wider shots that convey more context and action. They focus on larger segments of the body or surroundings and do not provide the intense detail or emotional nuance that a Close Up achieves. Thus, the essence of a Close Up lies in its ability to draw attention to intricate details, making it an essential tool in video production for storytelling and character development.
