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: smooth oval-section plain band, about 3.9 mm wide; balanced, minimal, and polished, neither too thin nor too heavy.
Material and visibility: bright glossy pale yellow gold with a neutral champagne tone, between silver and full yellow gold. Use high-contrast but physically realistic window reflections, including one small bright glint, so the ring remains noticeable in video and at distance.
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.
