Photorealistic jewellery campaign portrait, woman shot straight on, chest up, bare shoulders and collarbones exposed, arms crossed low, one hand on opposite shoulder, long black almond nails visible. Head level, neutral expression, dark hair slicked tight to skull. Face and body in deep soft shadow, near silhouette, features barely readable, no skin highlights. Sculptural gold neckpiece: three graduated polished wire arcs across collarbones, joined by fine articulated links, two small flush set off centre emeralds. One asymmetric earpiece: three linked gold bars descending from a slim hoop, ending in a single emerald. Stones catch the only direct light, glowing luminous green against darkness. Plain pale grey seamless studio background, evenly lit, much brighter than subject. Extreme low key underexposed lighting, soft falloff, no fill. Monochrome charcoal palette, green and gold as only accents. Minimal architectural luxury editorial. 85mm, high contrast, centred composition. --chaos 10 --ar 3:4 --exp 100 --raw --sref 2168441595 --profile 73hh66z --sw 1000 --stylize 400 --v 8.2
