Realistic Beach Portrait with Wet Hair

A realistic 9:16 beach portrait. A fictional adult woman, not a real person, appearing in her {argument name="age" default="mid-20s"}. Position the woman in the center of the screen, with the center of her face aligned to approximately 50% of the width, and the visual center including her wet hair, shoulders, and upper body also at 50%. The top of her head is just inside the upper edge, her face around the top 18%, her upper body in the center, with her leaning forward naturally connecting her arms and hands to the bottom. She faces the camera, lowering her hips and leaning forward slightly, laughing openly without shrugging. A bright smile that makes her eyes squint, mouth naturally open, teeth aligned but not overly uniform. Healthy contours, natural rounded cheeks, subtle glow on wet skin, and a bright complexion. Dark brown medium hair, nearly black, wet from seawater with thin strands irregularly along her forehead, temples, and cheeks, the rest flowing behind her shoulders. Do not make the hair voluminous or dry; draw wet clumps and tiny water droplets for each strand.

Her outfit is a solid {argument name="swimsuit color" default="deep navy blue"} halter neck bikini top. Express thin straps, natural fabric stretch, and subtle shades of wet fabric, avoiding excessive exposure or unnatural body exaggeration. The posture is innocent and sporty, making summer fun and freshness the main focus rather than sexiness. Both arms lowered in front of the body, with anatomically accurate connections of elbows, wrists, and fingers. Do not cut off important fingers at the edge; ensure five fingers per hand with natural overlap and joint direction.

Foreground is pale white sand and very shallow transparent seawater, the woman in the middle ground, and the background is a bright sea surface dissolving from white into light turquoise. Horizon lines and buildings are not emphasized, blurring the background into a clean, minimal aesthetic. Small white reflections and soft blue-green gradients on the sea surface, with tiny waves and bubbles near her feet. Camera slightly higher than the woman's chest, frontal, close range. Focal length around 50mm, natural perspective on face and upper body, no extreme wide-angle distortion. Shallow depth of field but face, hair, shoulders, and the front of the bikini are sufficiently resolved, with only the background smoothly blurred.

Light is a large, soft daylight like an overcast sky or bright shade from the top front. Avoid hard shadows, leaving uniform light on both sides of the face and faint shadows under the chin and inside the arms. Color temperature is slightly cool and neutral, exposure leaning high-key but without blowing out whites, and skin tone is natural. Overall color scheme is navy, white, and pale aqua blue. Natural pores, fine water droplets, and slight redness remain on the skin, avoiding excessive smoothing or plastic feel. Tiny, natural catchlights in the eyes, low moist gloss on the hair, and fine weave and wet texture on the fabric.

High-quality commercial photography, clean background, natural smile, realistic human body, consistent light and shadow. No text, logos, brand names, signatures, or watermarks. Avoid extra people, extra arms or fingers, missing fingers, fused hands, asymmetrical eyes, double teeth, unnatural chest area, melted fabric, floating droplets, doll-like skin, excessive HDR, over-sharpening, or illustrative style.

縦9:16の写実的なビーチポートレート。実在人物ではない架空の成人女性、見た目は{argument name="年齢" default="20代半ば"}。女性を画面中央に置き、顔中心を横幅の約50%、濡れた髪・両肩・上半身を含む視覚中心を横幅の約50%に合わせる。頭頂は画面上端のすぐ内側、顔は上部約18%付近、上半身は中央、前かがみで曲げた腕と手を下部へ自然につなぐ。女性はカメラ正面へ身体を向け、腰を落として軽く前傾し、肩をすぼめず開放的に大笑いする。目を細めるほど明るい笑顔、口を自然に開け、歯列は整っているが過度に均一にしない。健康的な輪郭、自然な頬の丸み、濡れた肌の控えめな艶と明るい血色。黒に近いダークブラウンのミディアムヘアは海水で濡れ、細い束が額・こめかみ・頬へ不規則に沿い、残りは肩の後ろへ流れる。髪を乾いたボリュームヘアにせず、一本ごとの湿った束感と小さな水滴を描く。

衣装は無地の{argument name="水着の色" default="深いネイビーブルー"}のホルターネックビキニトップ。細い肩ひも、自然な布の伸び、濡れた布のわずかな濃淡を表現し、過度な露出強調や不自然な身体誇張は避ける。姿勢は無邪気でスポーティー、色気ではなく夏の楽しさと爽快感を主役にする。両腕は身体の前へ下ろし、肘・手首・指のつながりを解剖学的に正確にする。重要な手指を画面端で切らず、指は各手5本、重なりと関節方向を自然にする。

前景は淡い白砂とごく浅い透明な海水、中景に女性、背景は白から淡いターコイズへ溶ける明るい海面。水平線や建物は強調せず、背景を清潔でミニマルにぼかす。海面には細かな白い反射と柔らかな青緑のグラデーション、足元近くにごく小さな波の泡を置く。カメラは女性の胸よりわずかに高い位置、正面、近距離。焦点距離感は50mm前後、顔と上半身に自然な遠近感、極端な広角歪みなし。被写界深度は浅めだが顔・髪・肩・ビキニの前面は十分に解像し、背景だけを滑らかにぼかす。

光は曇り空または明るい日陰のような大きく柔らかな昼光を正正面上方から当てる。硬い影を避け、顔の両側に均一な光、顎下と腕の内側にごく淡い影を残す。色温度はわずかに涼しいニュートラル、露出はハイキー寄りだが白飛びさせず、肌色は自然。全体の色調はネイビー、白、淡いアクアブルー。肌には自然な毛穴、微細な水滴、うっすらした赤みを残し、過剰な美肌処理やプラスチック感を避ける。瞳には小さく自然なキャッチライト、髪には湿った低い光沢、布には細かな織りと濡れた質感。

高品質な商用写真、清潔な背景、自然な笑顔、現実的な人体、整合する光と影。文字、ロゴ、ブランド名、署名、透かしを入れない。余分な人物、余分な腕や指、欠けた指、融合した手、左右非対称な瞳、二重の歯、不自然な胸元、溶けた布、浮いた水滴、人形のような肌、過度なHDR、過剰なシャープ、イラスト調を避ける。
