Use case: precise-object-edit
Input image: a localized crop from the original photograph. The transparent mask marks the base of the index finger, the uppermost long finger touching the cheek.
Primary request: add one new simple ring only inside the masked area, unmistakably wrapped around the index finger. Keep the original ring on the ring finger, so two rings remain visible.
Ring design: classic slim half-round comfort band, about 3.5 mm wide; moderate size, neither delicate enough to disappear in video nor chunky or crude.
Material and visibility: mirror-polished pale champagne yellow gold, halfway between silvery white metal and saturated yellow gold. Give it a crisp, bright specular highlight from the window so it remains noticeable as the person moves away, while still looking like real reflective metal rather than a glow effect.
Constraints: change only the masked index-finger ring area. Preserve the exact hand anatomy, finger pose, skin, existing ring, face, ear, hair, clothing, lighting, crop, camera, and every other pixel-level detail. No gemstones, engraving, extra jewelry, text, watermark, finger deformation, or beauty retouching.
