What term best describes a full face shot with headroom and room for the subject's shoulders?

A full face shot that includes headroom and space for the subject's shoulders is accurately described as a close-up. This type of shot focuses primarily on the subject's face, allowing the viewer to see facial expressions and details, which helps to convey emotions effectively. While a close-up emphasizes the facial features, it still accommodates the headroom—an essential aspect for aesthetic composition—and provides a glimpse of the shoulders, enhancing the visual context.

In contrast, a medium shot typically frames a subject from the waist up, allowing for more of the setting and body language to be visible but not focusing solely on the face. A wide shot encompasses a broader view of the scene, often including the entire subject and significant surroundings, which is not the case for a full face shot. A long shot extends this idea further, showcasing an even wider area that highlights the subject within a larger environment, making it less suitable for a detailed focus on the face. Thus, the term 'close-up' is indeed the most accurate representation of the described shot.
