Elegant Night Portrait in Japanese Modern Room

Subject: {argument name="subject" default="A night unraveling in the light"}

Main Figure:
A woman in her {argument name="age" default="20s"} is sitting deep in a wooden armchair, slightly to the right of the center of the screen. The figure occupies about 70% of the screen in a vertical portrait that captures her from the upper body down to her bare feet. One leg is tucked high on the seat, while the other flows to the side, balancing a calm adult allure with quiet tension.

Character/Expression:
Fair skin leaning towards light ivory-beige with a faint pink flush. Subtle highlights on the cheeks, tip of the nose, shoulders, and collarbone, preserving natural skin texture. Pale rose pink blush, champagne beige and pink brown eyeshadow, long slender eyelashes, natural under-eye bags, soft light-brown eyebrows, and a sheer pink-beige glossy lip. Small, clear catchlights in the eyes. The face is tilted slightly to the left of the screen, with a gaze directed quietly toward the camera. The expression is not too sweet, but rather a calm, mature atmosphere.

Clothing/Pose:
A mini dress with thin shoulder straps made of layered sheer material in {argument name="dress color" default="pale dusty rose"}. It features a deep but elegant V-neckline and a high-waisted cinched fit, with soft drapes falling naturally from the hips to the thighs. The skirt length is short, but maintains dignity through the layering of fabric. Her right hand is lightly placed over her collarbone with fingers naturally spread. Her left hand rests near the shin of the raised leg, with shoulders and wrists relaxed. One knee is pulled close to the chest, while the other leg is extended sideways along the seat, conveying a natural sense of gravity down to the toes.

Background/Lighting:
A quiet Japanese modern interior. Featuring taupe-colored plastered walls, dark wooden pillars, a shoji-style window in the back right with a small black vase and a modest branch arrangement. The background is dark and organized, without text or decorations. The main light is a soft, warm indoor lamp coming from the upper right of the screen. Thin beams of light hit the right side of the face, shoulder, collarbone, knee, and shin, while the other side falls into smooth shadows. Weak amber reflections are seen on the wooden furniture, leaving a large dark area on the left wall.

Composition/Camera:
4:5 aspect ratio. The camera is positioned slightly lower than the seated figure's chest, shot almost from the front. The face is placed at approximately 25% from the top of the screen, leaving wide negative space in the upper left. The back of the chair, both armrests, and the seat are visible, framing the body in a triangular silhouette. Focus is on the eyes and eyelashes, with the hair tips, dress hem, and background gently blurred. A natural compression feel equivalent to an 85mm lens with a shallow depth of field.

Texture/Style:
An elegant and mature photographic expression captured in a quiet Japanese modern interior. Hair is light milk tea ash brown with thin see-through bangs, a layered cut framing the face, and medium-long length reaching below the shoulders. Hair tips are loosely curled inward, carefully depicting each strand, fine highlights, soft sheen, and a small amount of natural flyaway hairs. Based on low-saturation browns and dusty pinks, with faint film grain, smooth gradations, and modest contrast. Avoids excessive skin smoothing, naturally depicting the textures of skin, wood, and thin fabric.

Negative:
Underage-looking person, unnatural face, unnatural gaze, extra fingers, missing fingers, fused limbs, broken joints, twisted legs, poor contact with props, unnatural gravity, shadows inconsistent with light source, overexposure, overly transparent fabric, plastic-like skin, text, logos, watermarks.

主題：
{argument name="主題" default="灯りにほどける夜"}

主体：
{argument name="年齢" default="20代"}女性が、画面中央やや右の木製アームチェアに深く腰掛けている。人物は画面の約70％を占め、上半身から素足までが入る縦長ポートレート。片脚を座面の上で大きく曲げ、もう片方の脚は横へ流し、落ち着いた大人の色気と静かな緊張感を両立させる。

人物・表情：
明るいアイボリーベージュ寄りの白肌に、ほんのりピンクの血色。頬、鼻先、肩、鎖骨には控えめなハイライトを入れ、自然な肌理を残す。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、視線は正面のカメラへ静かに向ける。表情は甘すぎず、落ち着いた大人びた雰囲気。

服装・ポーズ：
{argument name="ドレスの色" default="淡いダスティローズ"}のシアー素材を重ねた、細い肩紐のミニドレス。胸元は深めで上品なVネック、ウエスト位置は高めに絞り、柔らかなドレープが腰から太ももへ自然に落ちる。スカート丈は短めだが、布の重なりで品を保つ。人物自身の右手を鎖骨の上に軽く添え、指を自然に開く。左手は立てた脚のすね付近へ添え、肩と手首の力を抜く。片膝を胸元近くまで曲げ、もう片方の脚は座面に沿って横へ伸ばし、足先まで自然な重力を感じさせる。

背景・光：
落ち着いた和モダンの室内。灰褐色の塗り壁、濃い木の柱、右奥に障子風の窓と小さな黒い花器、控えめな枝ものを配置する。背景は暗く整理し、文字や装飾は入れない。主光は画面右上から入る暖色の柔らかな室内灯。顔の右側、肩、鎖骨、膝、すねに細い光を当て、反対側はなだらかな影へ落とす。木製家具には弱い琥珀色の反射光を入れ、左側の壁には広い暗部を残す。

構図・カメラ：
縦4:5。カメラは座った人物の胸より少し低い高さから、ほぼ正面で撮影。人物の顔を上から約25％の位置に置き、画面左上には広めの余白を残す。椅子の背、左右の肘掛け、座面まで見せ、人物の身体を三角形のシルエットにまとめる。焦点は両目とまつ毛に合わせ、髪先、ドレスの裾、背景は穏やかにぼかす。85mmレンズ相当の自然な圧縮感、浅めの被写界深度。

質感・スタイル：
静かな和モダンの室内で撮影した、上品で成熟した写真表現。髪は明るいミルクティーアッシュブラウン。薄いシースルーバング、顔まわりに沿うレイヤーカット、肩下までのミディアムロング。毛先は内側へ緩くカールし、一本一本の流れ、細いハイライト、柔らかな艶、少量の自然な後れ毛を丁寧に描く。低彩度のブラウンとダスティピンクを基調に、弱いフィルム粒子、滑らかな階調、控えめなコントラスト。過度な美肌補正を避け、肌、木材、薄布の質感を自然に描写する。

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、余分な指、欠けた指、手足の融合、関節の破綻、脚のねじれ、道具との接触不良、不自然な重力、光源と矛盾する影、過度な露出、透けすぎる布、プラスチックのような肌、文字、ロゴ、透かし。
