Young Woman in Semi-Open-Air Bath

Subject:
Hair unraveling on the water surface

Main Subject:
Vertical 2:3. A knee-up portrait of a {argument name="age and gender" default="woman in her 20s"} in a {argument name="setting" default="wooden semi-open-air bath"}, positioned slightly to the right of the center. The person occupies about 70% of the screen, kneeling in shallow water with both hands on the edge of the tub, leaning forward slightly.

Person/Expression:
Bright ivory-beige skin with natural texture and a faint flush. The face is directed towards the camera, chin slightly tucked, gazing quietly with clear eyes. Mouth slightly open, a calm and gentle expression. Pale rose pink blush, pink-brown eye shadow, thin natural eyelashes, subtle tear bags, light brown eyebrows, sheer pink-beige lips. Small catchlights in the eyes.

Clothing/Pose:
{argument name="clothing" default="A delicate ecru white crochet knit bikini"}. Carefully depict the thin shoulder straps, side ribbons, the sheerness of the knit, and the texture of wet fibers. Both arms are naturally extended, with palms placed on the stone edge of the tub. Fingers slightly open, weight distributed between knees and hands. Shoulders slightly inward, hips remaining back. The water surface touches halfway up the thighs, with small ripples spreading along the body's movement.

Background/Light:
A quiet semi-open-air bath surrounded by wooden pillars, old wood walls, bamboo screens, and small plantings. Light stone tub edge in the foreground, transparent hot water and the person in the midground, wooden architecture and blurred greenery in the background. Warm natural light shines from the top left, softly illuminating hair, cheeks, shoulders, collarbone, and water droplets. Faint reflected light from the wooden wall on the right. White fluctuations reflected on the water surface, with a thin shadow falling beneath the person.

Composition/Camera:
Vertical 2:3, small margin at the top of the head, cut at the tub edge at the bottom. A medium-close shot taken from a slightly high eye level. 50mm equivalent, focused on the face and upper body, with a natural background blur. Face at top center, guiding the diagonal lines of the arms downward, creating depth with the water surface and tub edge.

Texture/Style:
High-definition realistic portrait. Wet milk tea ash brown hair, thin see-through bangs, face-framing layers, medium-long hair down to the shoulders. Depict fine hair bundles, wet gloss, and natural stray hairs. Skin is not overly homogenized, leaving pores, fine water droplets, and cheek flush. A calm tone harmonizing warm wood, pale skin, deep green, and blue-green water surface.

Negative:
Minors, unnatural faces, unnatural gazes, excessive skin retouching, plastic-like skin, extra fingers, missing fingers, fused fingers, deformed arms or legs, broken joints, poor contact with the tub, unnatural floating, shadows inconsistent with the water surface, incorrect perspective, garbled text, logos, watermarks.

主題：
水面にほどける髪

主体：
縦長2:3。{argument name="場所" default="木造の半露天風呂"}に入る{argument name="年齢と性別" default="20代女性"}を、画面中央やや右に配置した膝上までのポートレート。人物は画面の約7割を占め、浅い湯の中で両膝をつき、浴槽の縁へ両手を置いて上体を少し前へ傾けている。

人物・表情：
明るいアイボリーベージュの肌に、自然な肌理と淡い血色を残す。顔はカメラへ正面気味に向け、顎をわずかに引き、澄んだ瞳で静かに見つめる。口元は軽く開き、落ち着いたやさしい表情。淡いローズピンクのチーク、ピンクブラウンのアイシャドウ、細く自然なまつ毛、控えめな涙袋、明るいブラウンの眉、透け感のあるピンクベージュのリップ。瞳に小さなキャッチライト。

服装・ポーズ：
{argument name="服装" default="生成りホワイトの繊細なクロシェ編みビキニ"}。細い肩紐とサイドリボン、編み目の透け感と濡れた繊維の質感を丁寧に描く。両腕は自然に伸ばし、左右の手のひらを浴槽の石縁へ置く。指は軽く開き、重心は両膝と両手へ分散。肩は少し内側へ入り、腰は後方に残る。水面が太腿の途中まで触れ、身体の動きに沿って小さな波紋が広がる。

背景・光：
木の柱、古材の壁、竹簾、小さな植栽に囲まれた静かな半露天風呂。前景に淡い石造りの浴槽縁、中景に透明感のある湯と人物、後景に木造建築とぼけた緑。画面左上から暖かな自然光が差し込み、髪、頬、肩、鎖骨、水滴を柔らかく照らす。右側には木壁からの淡い反射光。水面には白い揺らぎが映り、人物の下へ薄い影が落ちる。

構図・カメラ：
縦位置2:3、人物の頭頂に少量の余白、下端は浴槽縁で切る。やや高めの目線から撮影した中近景。50mm相当、顔と上半身に焦点を合わせ、背景は自然なボケ。顔を画面上部中央、両腕の斜線を下方向へ導き、水面と浴槽縁で奥行きを作る。

質感・スタイル：
高精細な実写ポートレート。濡れたミルクティーアッシュブラウンの髪、薄いシースルーバング、顔まわりのレイヤー、肩下までのミディアムロング。細い毛束、濡れた艶、自然な後れ毛を描写。肌は過度に均一化せず、毛穴、細かな水滴、頬の血色を残す。暖色の木材と淡い肌、深い緑、水面の青緑を調和させた落ち着いた色調。

ネガティブ：
未成年に見える人物、不自然な顔、不自然な視線、過度な美肌補正、プラスチックのような肌、余分な指、欠けた指、指の融合、腕や脚の変形、関節の破綻、浴槽との接触不良、不自然な浮遊、水面と矛盾する影、誤った遠近法、文字化け、ロゴ、透かし。
