Фотосессия на винтовой каменной лестнице особняка

Compose a vertical 9:16 ultra-photorealistic cinematic portrait of one person on an aged neoclassical limestone spiral staircase, evoking a historical European manor. Show weathered balusters, mineral deposits, moss growing in crevices, and textured stone steps marked by erosion. Render the image at 8k resolution with an 85mm prime lens and f/2.8 aperture. Use natural daylight diffused by an overcast sky, creating a soft-box effect and high dynamic range. Seat the person sideways on a mid-level limestone step and turn the torso slightly toward the camera. The right elbow rests casually on the raised knee, with a relaxed hand near the chin; place the left hand behind the body on the step for support. Keep the anatomy realistic, with a petite-to-average build, naturally curvy proportions, natural skin texture, and a lifelike physical presence. Dress the person in a midnight black silk charmeuse slip dress, bias-cut with liquid-like surface reflections. Add an oversized, chunky-knit deep obsidian cardigan with dropped shoulders and clearly visible purl stitches. A thin sterling silver anklet belongs on the right ankle. Base the person strictly on the reference photo. Treat that reference image as the strict guide to facial identity, retaining the face 1:1 as closely as possible. Preserve its exact structure and proportions, eyes, nose, lips, jawline, cheekbones, skin details, and overall likeness; do not change identity or any facial features in any way. Retain oval-to-heart facial morphology, a soft but defined jaw contour, pronounced cheekbone structure, and highly detailed natural eyes. Render visible pores, subtle natural skin irregularities, faint freckles, and lifelike subsurface light scattering for realistic skin.
