夏日阳台胶片人像

Use case: photorealistic-natural
Asset type: portrait image, intended aspect ratio 9:16
Primary request: Japanese negative film aesthetic, small balcony in summer, soft natural light, slight overexposure highlights, low contrast, faded colors, subtle grain. A fictional adult Korean female idol in her early 20s, refined and quietly magnetic, subtle sensuality through relaxed breathing and weight shift.
Scene/backdrop: narrow motel balcony with a pale curtain drifting through the door, distant low city roofs, plastic bag and room key on a small metal table.
Subject: leaning against the balcony rail with one hand behind her, torso angled toward open sky, hair moving over one eye.
Wardrobe/props: peach oversized cotton shirt loosely unbuttoned at the collar, white high-waisted shorts, cold glass bottle of mineral water lifted near her lips.
Composition/framing: tall vertical crop, slightly too close at the top, raw film snapshot feeling.
Lighting/mood: morning haze, intimate but non-explicit, quiet.
Constraints: fictional adult subject only; no real celebrity likeness; no visible brand marks, no text, no watermark.

使用场景：照片级写实自然风格

素材类型：人像图像，预期宽高比 9:16

主要要求：日式底片胶片风格，夏季小阳台，柔和自然光，高光略微过曝，低对比度，色彩柔和，颗粒感轻微。一位虚构的二十出头的韩国成年女偶像，气质优雅，散发着一种静谧的魅力，通过放松的呼吸和重心转移展现出微妙的性感。

场景/背景：狭窄的汽车旅馆阳台，浅色窗帘从门后飘出，远处是低矮的城市屋顶，一张小金属桌上放着塑料袋和房卡。

人物：倚靠在阳台栏杆上，一只手放在身后，上半身朝向天空，头发拂过一只眼睛。

服装/道具：一件桃色宽松棉质衬衫，领口敞开，白色高腰短裤，一瓶冰镇矿泉水举到唇边。

构图/取景：竖幅高角度裁剪，顶部略微靠前，营造出胶片快照般的原始感。
