Generate Charcoal Turtleneck Studio Portraits

Photorealistic portrait of the subject from the waist up, positioned centrally against a deep charcoal grey seamless paper backdrop — no set dressing, no props, nothing competing with the subject. The subject wears a tailored black turtleneck, posture upright, looking directly into the camera. Large softbox positioned high and slightly to one side acts as the key light — broad, sculpted, producing a clean shadow under the cheekbone and jaw while keeping the face fully readable. A second fill card on the opposite side opens the shadow to a 3:1 ratio, and a hair light from directly above separates the subject cleanly from the backdrop. Shot on Phase One IQ4 150MP with Zeiss Otus 85mm f/1.4, f/4.0 aperture, 1/200s shutter speed, ISO 100. Detailed turtleneck rib texture with fine jersey knit structure, shoulder seam precision, the subtle texture of the seamless paper ground visible behind. Skin with natural subsurface warmth under the softbox key, visible pores, sharp catchlights from the large source. Avoid any environmental effect on the subject's face, avoid plastic or airbrushed skin, avoid any color cast on the backdrop, avoid text and watermarks. 2:3 aspect ratio.
