Japanese Woman Poolside Portrait

Subject:
{argument name="subject" default="Light unraveling on the water surface"}

Main Subject:
Depict one {argument name="person" default="Japanese woman in her early 20s"} sitting on the stone edge of a bright outdoor pool. The person is placed slightly to the right of the center, in a near-full-body portrait showing head to toe. The person occupies about 70% of the screen, with turquoise blue water and open white space widely left on the left side.

Character/Expression:
Bright ivory-beige white skin. Smooth texture with a hint of natural pink flush and visible skin grain. Apply soft highlights to the cheeks, tip of the nose, shoulders, and collarbones. Dark brown hair tied in a high loose bun, leaving thin see-through bangs and stray hairs around the face. Pale rose pink blush, champagne beige and pink brown eyeshadow, long thin eyelashes, natural eye bags, soft light brown eyebrows, and sheer pink beige glossy lips. Small clear catchlights in the pupils. Face tilted slightly to the left of the screen, lips slightly open, looking at the camera with a gentle gaze.

Clothing/Pose:
Light ivory halter neck bikini. The top has fine vertical gathers and soft volume, and the bottom is an elegant design tied with thin strings on both sides. The body is a well-proportioned model figure typical of a mature woman, with natural curves at the waist and chest while keeping the thighs slim to balance the full body ratio. Sitting shallowly on the stone edge, both knees bent and extended towards the front left of the screen. The person's left arm is bent overhead, fingertips lightly touching the bun. The right hand rests on the stone surface beside the body, quietly supporting the weight. Shoulder and waist slightly twisted, leaning the back against a pillar.

Background/Light:
{argument name="background" default="Outdoor pool of a modern Japanese private villa"}. Pale beige stone pillar on the right, transparent turquoise blue water surface on the left. In the mid-ground, a low-rise building combining white walls and wood; in the background, small potted trees and deep greenery. Summer sunlight enters from the top left, not too strong, illuminating the face, shoulders, chest, and top of the legs. Soft shadows remain on the pillar side, with pale blue reflected light from the water surface thinly showing on the underside of the legs and waist.

Composition/Camera:
Vertical 3:4. Full-body portrait taken from a position slightly lower than eye level. Move the person to the right side of the screen to create depth in the pool on the left. Natural compression equivalent to 70-85mm. The face and upper body are the sharpest, with the background gently blurred. Feet are naturally contained at the bottom of the screen, with a small amount of space left overhead.

Texture/Style:
High-definition realistic portrait. Bright and clean summer resort photo. Skin is not overly homogenized, leaving fine texture and natural flush. Delicate depiction of water reflections, fine irregularities in the stone, bikini gathers, and individual strands of hair. Soft contrast, with transparent tones based on pale ivory and turquoise.

主体：
明るい屋外プールの石造りの縁に腰掛ける、{argument name="人物" default="20代前半の日本人女性"}を一人描く。人物は画面中央やや右に配置し、頭頂から足先まで入る全身寄りのポートレート。人物が画面の約7割を占め、左側にはターコイズブルーの水面と開放的な余白を広く残す。

人物・表情：
明るいアイボリーベージュ寄りの白肌。ほんのりピンクの血色を含み、自然な肌理を残したなめらかな質感。頬、鼻先、肩、鎖骨に柔らかなハイライトを入れる。ダークブラウンの髪を高めのゆるいお団子にまとめ、薄いシースルーバングと顔まわりの後れ毛を残す。淡いローズピンクのチーク、シャンパンベージュとピンクブラウンのアイシャドウ、細く長いまつ毛、自然な涙袋、明るめブラウンの柔らかな眉、透け感のあるピンクベージュのグロスリップ。瞳には小さく澄んだキャッチライト。顔をわずかに画面左へ傾け、唇を軽く開き、穏やかな視線でカメラを見る。

服装・ポーズ：
淡いアイボリー色のホルターネックビキニ。トップは細かな縦ギャザーと柔らかな立体感があり、ボトムは両脇を細い紐で結ぶ上品なデザイン。身体は成熟した女性らしい均整の取れたモデル体型で、腰と胸元に自然な曲線を持たせつつ、大腿部はすっきり細めで全身の比率を整える。石の縁に浅く腰掛け、両膝を曲げて画面左前方へ伸ばす。人物自身の左腕を頭上へ曲げ、指先でお団子に軽く触れる。右手は身体の横の石面につき、体重を静かに支える。肩と腰を少しひねり、背中を柱へ預ける。

背景・光：
{argument name="背景" default="和モダンなプライベートヴィラの屋外プール"}。右側に淡いベージュの石柱、左側に透明感のあるターコイズブルーの水面。中景には白壁と木材を組み合わせた低層建築、後景には丸い鉢植えの小さな樹木と深い緑。画面左上から強すぎない夏の日差しが入り、顔、肩、胸元、脚の上面を照らす。石柱側には柔らかな陰影を残し、水面からの青白い反射光を脚と腰の下側へ薄く映す。

構図・カメラ：
縦3:4。目線よりわずかに低い位置から撮影した全身ポートレート。人物を画面右側に寄せ、左側のプールに奥行きを作る。70〜85mm相当の自然な圧縮感。顔と上半身を最もシャープにし、背景は穏やかにぼかす。足先は画面下部に自然に収め、頭上には少量の余白を残す。

質感・スタイル：
高精細な実写ポートレート。明るく清潔な夏のリゾート写真。肌は過度に均一化せず、細かな肌理と自然な血色を残す。水面の反射、石材の細かな凹凸、ビキニのギャザー、髪の一本一本を繊細に描写。柔らかなコントラスト、淡いアイボリーとターコイズを基調にした透明感のある色調。
