Photorealistic jewellery campaign portrait, woman shot straight on chest up, bare shoulders and collarbones exposed, arms crossed low with one hand on opposite shoulder, long black almond nails visible. Head level, neutral expression, dark hair slicked tight to skull. Face and body as deep soft shadow, features barely readable in silhouette, no skin highlights. Wearing an architectural brushed silver collar of two asymmetric interlocking angular plates at the throat, slim chain dropping to a single recessed baguette cut ruby at the collarbones; matching earpiece of two stacked silver arcs holding a small suspended ruby. Stones catch the only direct light, glowing deep crimson against darkness. Plain pale grey seamless studio background, evenly lit, much brighter than subject. Extreme low key underexposed lighting, soft falloff, no fill, near silhouette rendering. Monochrome charcoal palette, crimson and silver as only accents. Minimal architectural luxury editorial. 85mm, high contrast, centred composition. --chaos 10 --ar 3:4 --seed 87644477 --exp 100 --raw --sref 2168441595 --profile 73hh66z --sw 1000 --stylize 400 --hd --v 8.2
