老人制陶（双手特写纪录片） prompt

Subject: an elderly craftsman's hands on a potter's wheel. Action: extreme close-ups alternate - fingers pressing into wet clay, water spreading across the spinning surface, the form rising and narrowing under steady pressure; the camera never cuts to his face, only hands. Scene: a small workshop with a window. Light: natural window key from one side, deep ambient shadow. Camera: locked macro and over-the-shoulder hand-level close-ups, no shake. Style: photoreal documentary, intimate. Audio: low hum of the wheel, wet clay sounds, distant birdsong from an open window, no music, no narration. Constraints: no watermark, no on-screen text, no extra hands.
