    "prompt": "An intimate documentary photograph of an elderly violin restorer in a small lived-in workshop, viewed from slightly above bench height. The craftsman wears a faded indigo work shirt and round spectacles, leaning forward to inspect the curved varnished body of one antique violin resting on a folded linen cloth. One hand steadies the violin gently while the other holds a small inspection light. A large window on the left casts soft directional afternoon daylight across his lined face, amber wood grain, delicate wood shavings, a steel chisel and worn workbench. A few unfinished violin shapes hang softly out of focus in the background. Quiet concentration, believable hands and tools, rich natural material textures, subtle film grain, restrained warm colors, one coherent scene, no staged product display, no lettering, no logos, no watermark.",
