Black and White Studio Portrait of Young Woman in Japanese School Uniform

Ultra-realistic black and white studio portrait photography, a young East Asian woman in her 20s kneeling on the floor of a minimalist white photography studio, vertical composition, approximately 2:3 ratio, medium to full body framing, subject positioned center-right, occupying 65%-70% of the frame. She sits in a Japanese seiza pose or with legs folded beneath her, feet naturally together behind, wearing pure white short socks; upper body slightly turned to the left side of the frame, back naturally straight, hands gently resting on knees or thighs. She looks back at the camera, expression calm, gentle, confident, with a very slight smile, overall demeanor restrained, fresh, not exaggerated. She has a delicate soft oval face, natural jawline, dark almond eyes, slender straight nose, naturally full lips. Makeup is extremely light, suitable for black and white photography: sheer foundation, natural eyebrows, subtle eyeliner and lashes, soft lip shape, no heavy makeup. Long thick dark hair falls naturally to chest or waist, with slight waves; front has light airy bangs and face-framing strands, hair smooth but retaining natural fluffiness and a few flyaways. She wears Japanese school uniform style clothing: white collared shirt as inner layer, over it a dark crew neck or V-neck long-sleeve knit sweater, lower body a dark pleated plaid skirt, skirt naturally flaring into clear radiating pleats. A low-key tie or thin ribbon is visible at the neck. Feet in pure white mid-calf socks, no shoes. Clothing is neat, realistic, no logos, no text, no exaggerated decoration, maintaining natural proportions of everyday school uniform. Background is a minimalist white or light gray seamless studio, floor and wall naturally merging, no other furniture or people. Upper left of frame has a strong but softened diagonal window light or large spotlight, creating a clear large geometric bright area and soft shadow edges on the wall; subject lit evenly from front-left soft light, face and hair retaining detail. Overall pure black and white or neutral grayscale, high-key but not overexposed, dark clothing with rich shadow detail, skin tone transitioning through fine mid-grays and highlights. Use 85mm or 70-85mm portrait lens, f/2.8-4, ISO 100-200, 1/200s, medium depth of field. Eyes, face, bangs, knit texture, pleated skirt and sock details sharp, background smooth and clean.
