Photorealistic B&W Portrait of Adult East Asian Woman

2:3 vertical, photorealistic black-and-white portrait photography. An adult East Asian woman, clearly 22-28 years old, appears in a close-up composition from shoulders to upper chest, body slightly turned to the right side of the frame, head gently turned to the left front, gaze looking past the camera into the distance, not directly at the lens. Expression is calm, restrained, with a hint of detachment and contemplation, lips naturally closed, not smiling. She has a refined oval face, soft but defined jawline, dark almond-shaped eyes, natural double eyelids, slender eyebrows, straight elegant nose bridge, full but restrained natural lips. Facial proportions are realistic, no exaggerated eyes or doll-like features. Long thick dark hair falls naturally to chest and back, slightly parted in the middle, lightly tousled, some strands falling on the sides of the face and shoulders, retaining realistic hair layers and fine flyaways. She wears a black high-neck semi-transparent lace top, fitted cut, shoulders and arms covered with intricate floral lace texture, lace has realistic cutouts and fiber details; the high collar part is of denser black fabric, creating layers with the transparent lace. Overall styling is minimalist, no obvious jewelry, no logo. Background is a minimalist photo studio or indoor gray gradient wall, transitioning from brighter mid-gray at the lower left to dark gray-black at the upper right, no props. Main light is a large softbox or soft window light from the left front, creating classic side lighting, illuminating the left side of the face, nose bridge, cheekbone, and lips, with soft shadows on the right side of the face; the right side of the hair blends naturally with the background. Black-and-white tones emphasize rich grays, soft highlights, and deep but detailed shadows. 85mm portrait lens, f/1.8-2.2, ISO 200-400, extremely shallow depth of field, precise focus on eyes and face, shoulder lace texture sharp, hair and background away from the focal plane softly blurred. Overall low-contrast black-and-white tone with slight silver gelatin print texture, fine ISO 400 grain, soft highlight roll-off, and slight vignette. Realistic skin pores, tiny vellus hair, natural skin texture, hair and lace fibers, fine-art monochrome portrait, cinematic editorial photography, quiet melancholy, photorealistic, natural imperfections, no plastic skin, no excessive retouching, no exaggerated eyes, no text, no logo, no watermark.
