"headroom" 的定义和意义

What is "headroom"?

Headroom is the amount of space between the top of a subject's head and the upper edge of the frame in a photograph or video. Proper headroom ensures that the subject is well-composed within the image, avoiding a cramped or overly open look. Too little headroom can make the subject feel cramped or cut off, while too much can create an unbalanced appearance. Achieving the right amount of headroom helps maintain a pleasing and professional composition.
