The locket is open, showing a small photo inside the top half. The gold finish is highly polished with realistic specular highlights, micro-scratches, and accurate reflections. The chain is visible and neatly draped above the pendant.\n\nThe inner photo: a small black-and-white candid couple portrait (if an insert photo reference is provided, use that exact image; otherwise generate a tasteful B&W couple photo). The photo must fit naturally behind the locket window with correct perspective, slight glass reflection, and realistic paper texture.\n\nThe open bottom half of the locket shows a clean, reflective gold interior with hinge details and realistic depth. Fabric background is a matte black knit/cotton texture with visible weave, subtle lint fibers, and soft folds.\n\nLighting: premium product lighting with a soft key and gentle fill; warm highlights on gold; controlled shadows; no harsh glare blowing out details. Camera: macro lens look with shallow depth of field - locket and photo sharp, edges gently fall off. Mood: elegant, intimate, gift-ready, high-end campaign aesthetic." }, "hard_constraints": [ "Single product only: one gold heart locket necklace, open.", "Photoreal macro detail: metal reflections, hinge, chain, fabric weave.", "Photo inside locket must look printed and physically placed (not floating).", "No readable text, no logos, no watermark.", "No extra jewelry items, no hands." ], "negative_prompt": [ "text, logos, watermark", "extra jewelry", "hands or people holding it", "cartoon, CGI", "plastic-looking gold", "blown highlights", "blurry photo inside locket", "warped locket shape", "low resolution" ] } }
