Morning Sunlight Roomwear Portrait

Subject: {argument name="theme" default="Morning light on damp hair"}

Subject: A vertical portrait of an {argument name="person" default="adult woman in white roomwear"} sitting on a rug by a bright window. The subject is positioned largely from the center to the right of the screen, showing from the top of the head to the thighs. The upper body occupies about two-thirds of the screen, leaving a soft background margin and the window on the left.

Character/Expression: Natural black semi-long hair. Thin strands of hair, slightly damp as if after a bath, run along the cheeks and neck, with thin bangs falling over the forehead. The head is slightly tilted toward the upper left of the screen, with a quiet gaze directed out the window. Relaxed eyes, slightly parted lips, and a calm expression with a hint of sleepiness remaining. Minimal makeup centered on pale beige and pink, showing natural skin with pores and fine hair.

Clothing/Pose: A white camisole with thin shoulder straps and delicate lace, and matching shorts. Small buttons and soft gathers at the chest, with the light fabric falling naturally with gravity. A cream-colored, coarsely knitted cardigan is dropped from the shoulders, hanging loosely over the elbows and forearms. The body is twisted slightly to the left, sitting with one leg bent toward the front in a natural posture with slightly offset shoulder heights.

Background/Light: A large window on the left. Outside the window, green leaves bathed in morning sun spread out in soft bokeh. A white cup, a small glass vase, and thin branches are placed sparingly on a wooden table by the window. The primary light is warm natural light streaming from the window at the top left. It creates soft highlights on the cheeks, bridge of the nose, collarbone, shoulders, arms, and thighs, while the right side of the hair and the back of the room sink into gentle shadows. Pale reflected light bounces back from the white cloth and floor.

Composition/Camera: Vertical 2:3. Close-up shot looking down from a slightly high position. A triangular composition with the face at the top center, the chest in the center, and the bent leg at the bottom left. The margin on the window side emphasizes the direction of the gaze, and the background is heavily blurred. 50mm equivalent, shallow depth of field near wide open. Focus is on the eyes and face, with the leg in the foreground and the window in the background softly blurred.

Texture/Style: A photorealistic indoor portrait shot only with natural light. Based on bright ivory and pale wood grains, with healthy skin tones and the green outside the window as subtle accent colors. Not overly smoothed, but precisely depicting skin texture, fine hair, the clumped feeling of damp hair, and the fibers of lace and knit. Low contrast with soft gradations like an elegant film photograph.

Negative: Underage-looking persons, unnatural faces, unnatural gazes, asymmetrical eyes, extra fingers, missing fingers, fusion of limbs, collapsed shoulders or joints, clothing digging in, unnatural transparency of fabric, hair or clothing defying gravity, shadows inconsistent with light sources, excessive skin correction, plastic-like skin, text, logos, watermarks.

主題：
{argument name="テーマ" default="濡れ髪に朝光"}

主体：
{argument name="人物" default="白いルームウェア姿の成人女性"}が、明るい窓辺のラグに座っている縦長ポートレート。人物は画面中央からやや右に大きく配置し、頭頂から太ももまでを写す。上半身が画面の約3分の2を占め、左側には窓と柔らかな背景の余白を残す。

人物・表情：
自然な黒髪のセミロング。入浴後のように少し湿った細い毛束が頬や首筋に沿い、薄い前髪が額にかかっている。頭を画面左上へわずかに傾け、窓の外へ静かに視線を向ける。力の抜けた瞳、わずかに開いた唇、眠気が残る穏やかな表情。淡いベージュとピンクを中心にした控えめなメイクで、毛穴や産毛を残した自然な肌。

服装・ポーズ：
細い肩紐と繊細なレースをあしらった白いキャミソールと、同素材のショートパンツ。胸元には小さなボタンと柔らかなギャザーを入れ、薄手の布が自然な重力に沿って落ちる。生成り色のざっくり編みカーディガンを肩から落とし、両腕の肘から前腕にゆるく掛ける。身体は画面左へ少しひねり、片脚を手前に曲げて座り、肩の高さをわずかにずらした自然な姿勢。

背景・光：
左側に大きな窓。窓の外には朝日を浴びた緑の葉が柔らかな玉ぼけとなって広がる。窓辺の木製テーブルに白いカップ、小さなガラス花器、細い枝を控えめに置く。主光は画面左上の窓から差し込む暖かな自然光。頬、鼻筋、鎖骨、肩、腕、太ももに柔らかなハイライトを作り、髪の右側と室内奥は穏やかな陰影に沈める。白い布と床から淡い反射光が返る。

構図・カメラ：
縦2:3。やや高い位置から見下ろす近距離撮影。人物の顔を上部中央、胸元を中央、曲げた脚を左下に置く三角形構図。窓側の余白で視線の方向を強調し、背景は大きくぼかす。50mm相当、開放寄りの浅い被写界深度。瞳と顔に焦点を合わせ、前景の脚と背景の窓辺は柔らかくぼかす。

質感・スタイル：
自然光だけで撮影したフォトリアルな室内ポートレート。明るいアイボリーと淡い木目を基調に、肌の血色と窓外の緑を控えめな差し色にする。過度に滑らかにせず、肌理、細い産毛、湿った髪の束感、レースとニットの繊維を精密に描写。低コントラストで、上品なフィルム写真のような柔らかな階調。

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、左右非対称な瞳、余分な指、欠けた指、手足の融合、肩や関節の破綻、衣服の食い込み、布地の不自然な透過、重力に反する髪や衣服、光源と矛盾する影、過度な美肌補正、プラスチックのような肌、文字、ロゴ、透かし。
