What is the space between the subject and the top edge of the frame called?

The space between the subject and the top edge of the frame is referred to as headroom. This term is crucial in framing a shot properly, as it ensures that the subject's head is not cut off at the top, providing a balanced look to the composition. Maintaining appropriate headroom contributes to the visual appeal and readability of the image, allowing the viewer to focus on the subject without distraction.

In filmmaking and photography, proper headroom creates a sense of comfort and naturalness in the shot, helping to establish the right context and perspective. The other options, while relevant in different contexts, do not specifically refer to the space above the subject’s head. For example, nose room pertains to the space in front of a subject's face, typically in profile shots, while lead room refers to the space in front of a moving subject or when a subject is looking or moving towards one side of the frame. Vertical space, though a more general term, does not specifically address the particular area above the subject.
