Hotel Bathroom Mirror Selfie

Subject: Mirror selfie showing the back.

Main Subject: An adult woman sitting sideways on the edge of a washstand counter in a bathroom reminiscent of a high-end urban hotel, taking a selfie through the mirror. The figure occupies a large portion from the center to the left, capturing her from head to mid-thigh in a 9:16 vertical ratio. She holds a {argument name="smartphone" default="latest generation triple-camera smartphone in Desert Gold"} in her right hand, aiming it toward the mirror on the right side of the frame.

Person & Expression: A woman with natural transparency and a calm, mature look. Her hair is a {argument name="hairstyle" default="glossy dark chocolate brown bob cut just below the jaw"}. The ends curve slightly inward, with thin bangs and fine wisps along her cheeks softly framing her face. She has pale pink-beige blush, delicate brown eye makeup, natural under-eye bags, and glossy rose-beige lips. Her face is tilted slightly toward the bottom right as she looks down at the smartphone screen with a quiet and peaceful expression.

Clothing & Pose: {argument name="outfit" default="a summer mini dress made of fine ivory white ribbed material that naturally follows the body's lines"}. The neckline is a modest V, and the back has a deep V-cut opening from the shoulder blades to the waist area. No fabric or decoration is placed in the center of the back, clearly showing smooth lines. She pulls her left shoulder toward the mirror, slightly twisting her upper body. Her waist is stabilized on the counter, with both legs flowing together toward the right. Her right elbow is bent to keep the smartphone at face height, fingers naturally gripping the side of the device.

Background & Light: A clean bathroom with beige marble tiles, a glass shower booth, greige vanity storage, and a white ceramic bowl. A small wall-mounted washbasin and chrome piping are positioned in the center background. Warm-colored downlights on the ceiling and lighting around the mirror serve as primary light sources. These softly illuminate the person's face, shoulders, and upper back, casting gentle shadows to the left of the waist and under the counter. Subdued reflections are seen on the tiles and the metal surfaces of the smartphone.

Composition & Camera: 9:16 vertical orientation, a close-range mirror portrait from the waist up to the thighs. A little space is left at the top above the head, with the waist and hip lines positioned in the lower half of the screen. The camera is at eye level, roughly the same height as the mirror. A natural perspective equivalent to 50mm, focusing on the face and smartphone. The background is lightly softened while keeping the bathroom fixtures distinguishable.

Texture & Style: Live-action fashion photography. Carefully represents natural skin texture, the stretch and wrinkles of the fine ribbed fabric, the shine of individual hair strands, and reflections from polished marble and metal. The color tone is refined and hotel-like, based on warm ivory and beige with low saturation. Avoids excessive sharpening or skin retouching to maintain a sense of reality as if taken with a smartphone.

主題：
鏡越しの背中

主体：
上質な都市型ホテルを思わせるバスルームで、洗面カウンターの縁に横向きで腰掛け、鏡越しにセルフィーを撮る架空の成人女性。人物は画面中央から左側を大きく占め、頭部から太腿までを縦長9:16で収める。右手に{argument name="スマートフォン" default="デザートゴールドの最新世代トリプルカメラ搭載スマートフォン"}を持ち、画面右寄りの鏡へ向ける。

人物・表情：
自然な透明感と落ち着いた大人っぽさを持つ女性。髪は{argument name="髪型" default="艶のあるダークショコラブラウンの顎下ボブ"}。毛先は軽く内側へ入り、薄い前髪と頬に沿う細い後れ毛が顔を柔らかく縁取る。淡いピンクベージュのチーク、繊細なブラウンアイメイク、自然な涙袋、艶のあるローズベージュの唇。顔は画面右下へ少し傾け、伏し目がちにスマートフォンの画面を見る。表情は静かで穏やか。

服装・ポーズ：
{argument name="服装" default="アイボリーホワイトの細かなリブ素材を使った、身体に自然に沿う夏用ミニワンピース"}。首元は控えめなVライン、背面は肩甲骨から腰付近まで深く開いた大きなV字バック。背中の中央には布や装飾を置かず、滑らかなラインを明確に見せる。左肩を鏡側へ引き、上半身を軽くひねる。腰をカウンターに安定させ、両脚は画面右方向へそろえて流す。右肘を曲げてスマートフォンを顔の高さに保ち、指は端末の側面を自然につかむ。

背景・光：
ベージュの大理石調タイル、ガラス張りのシャワーブース、グレージュの洗面収納、白い陶器ボウルを備えた清潔なバスルーム。背景中央に小型の壁付け洗面器とクローム配管を配置する。天井の暖色ダウンライトと鏡周囲の照明が主光源。人物の顔、肩、背中の上部を柔らかく照らし、腰の左側とカウンター下へ穏やかな影を落とす。タイルとスマートフォンの金属面に控えめな反射を入れる。

構図・カメラ：
縦長9:16、腰上から太腿までの近距離ミラーポートレート。人物の頭頂は上端から少し余白を取り、腰とヒップラインを画面下半分に配置。カメラは鏡とほぼ同じ高さの平視。50mm相当の自然な遠近感で、顔とスマートフォンに焦点を合わせる。背景は軽く柔らかくしながら、浴室設備の形は判別できる程度に残す。

質感・スタイル：
実写ファッション写真。自然な肌理、細かなリブ生地の伸縮と皺、髪の一本一本の艶、磨かれた大理石と金属の反射を丁寧に表現。暖かいアイボリーとベージュを基調に、低彩度で上品なホテルライクの色調。過度なシャープ処理や美肌補正を避け、スマートフォンで撮影したような現実感を残す。
