A "close-up" is a type of shot in photography and film that captures a subject from a very short distance. This technique emphasizes details, allowing viewers to see features that might be missed in wider shots. Close-ups are often used to convey emotions or highlight important elements in a scene. In the context of cinematography, close-ups can enhance storytelling by focusing on a character's facial expressions or significant objects. This technique draws the audience's attention and creates a more intimate connection with the subject, making it a powerful tool in visual media.
