自然光人像自拍

Ultra-realistic candid smartphone selfie portrait of a young East Asian woman sitting indoors beside a large window during bright natural daylight. Maintain strong facial resemblance to the uploaded facial reference: soft oval face shape, delicate jawline, naturally narrow nose bridge, lightly defined lips, subtle cheek structure, realistic eye spacing, calm relaxed expression, and authentic skin tone with visible natural texture and pores. Preserve realistic asymmetry and avoid beauty enhancement or stylization. The subject is positioned in a close-up three-quarter side profile, looking slightly outward toward the window with a calm contemplative gaze. Expression is neutral and natural, with relaxed eyelids and soft mouth tension. No exaggerated emotion or posed glamour expression. Hair is long, dark black-brown, naturally thick and slightly tousled, falling over the shoulders with soft uneven strands catching sunlight. Hair texture appears realistic with individual flyaway strands visible in backlight. She wears oversized round black eyeglasses with glossy plastic frames. Outfit is a simple fitted light gray short-sleeve t-shirt made from soft cotton fabric with realistic folds, stretching, and natural fabric compression around the shoulders and torso. Lighting is strong directional morning or afternoon sunlight entering from the right-side window, producing realistic high-contrast illumination across the face and arms. Preserve natural shadow bands from the window frame cast diagonally across the skin. Highlights should remain physically accurate without HDR overprocessing. Skin should show realistic subsurface scattering, mild shine on illuminated areas, and natural tonal variation. Environment is minimal and realistic: pale neutral-colored interior wall beside a vertical window frame. No decorative background elements. Maintain the quiet candid indoor atmosphere. Camera behavior should mimic a real smartphone front-camera selfie: vertical 9:16 composition slightly low camera angle from arm's-length perspective mild wide-angle distortion on the foreground arm shallow but realistic smartphone depth of field natural exposure rolloff authentic digital image grain/noise realistic lens softness and contrast behavior Composition preserves: subject occupying center-left frame extended arm visible in foreground window on right edge tight crop around upper torso and head candid non-professional framing Photographic realism priority: authentic skin texture realistic optical imperfections physically correct anatomy natural lighting behavior no CGI appearance no cinematic color grading no artificial sharpness no beauty retouching no stylized anime or influencer aesthetic.
