What does head room refer to in framing a shot?

Head room refers to the distance from the top of a person's head to the top of the frame in a shot. This concept is crucial in framing images because it helps create a balanced composition that feels visually pleasing and appropriately focused on the subject. If there is too much head room, the subject may appear small or distant in the frame; if there is too little, the subject's head might get cut off, creating an awkward or unprofessional look. Proper use of head room contributes to the overall aesthetics and effectiveness of a shot, guiding the viewer's eye and ensuring the intended focus on the subject is maintained.
