"intent": "Generate a hyper-idealized, 'Douyin-aesthetic' portrait of a young woman at night, utilizing direct flash photography to create a high-contrast, ethereal look with clear weather conditions.",
"frame": {
"aspect_ratio": "9:16",
"composition": "Extreme close-up selfie framing (tighter than standard portrait), cutting off the top of the forehead to focus intensely on the eyes and lips. The subject is centered with a direct, confronting gaze.",
"style_mode": "Flash photography, digital influencer aesthetic, soft-focus realism."
},
"subject": {
"identity": "A young Asian woman, approximately 20 years old, with hyper-symmetrical, doll-like features characterized by the 'bunny tongue' and 'puppy eye' aesthetic.",
"skin": "Pale, cool-toned porcelain complexion with zero texture. The skin reflects the flash, creating a 'mochi' or 'glass skin' effect that appears soft and translucent. High-key brightness on the T-zone.",
"eyes": "Large, round eyes with a slight downward tint at the outer corners (puppy dog eyes). Prominent 'aegyosal' (under-eye fat bands) are highlighted to enhance youthfulness. The irises are soft brown with a large diameter. Eyelashes are styled in the 'manhwa' or 'idol' style: distinct, vertical clumps of mascara-coated lashes separated by space, rather than a dense fan.",
"nose": "Petite, low-bridge nose with a small, rounded tip. The lighting minimizes the nostril definition, making the nose appear delicate and unobtrusive.",
"mouth": "Heart-shaped lips featuring a 'gradient lip' technique. The center of the lips is a saturated, glossy strawberry pink, fading outward to a blurred, pale nude at the vermilion border. The texture is soft and hydrated.",
"hair": "Long, silky jet-black hair with a straight texture. Without the snow, the hair is dry, sleek, and tucked slightly behind the ears or framing the face smoothly, catching the flash with a white sheen.",
"wardrobe": "Minimal visibility, suggesting a stylish but casual top appropriate for a pleasant evening."
},
"environment": {
"location": "Urban night setting.",
"weather": "Clear, calm, and beautiful night weather. The atmosphere is clean and free of precipitation or fog.",
"background": "A backdrop of deep black shadows punctuated by creamy, circular bokeh from distant city lights (streetlamps, neon signs). The background is significantly darker than the subject, ensuring the face is the sole focus."
},
"lighting": {
"type": "Direct, frontal camera flash or high-intensity screen light.",
"quality": "Hard but flattering light that flattens facial topography, eliminating shadows under the eyes and nose. This creates a 2D, illustrative quality common in high-end social media selfies.",
"contrast": "High contrast between the brightly illuminated face and the pitch-black environment.",
"catchlight": "Sharp, tiny pinpoint reflection in the center of the pupils from the flash."
},
"camera": {
"sensor_format": "Smartphone main sensor simulation.",
"lens": "24mm wide-angle lens. This focal length slightly exaggerates the size of the eyes and diminishes the size of the nose and face width, contributing to the 'baby face' proportion.",
"aperture_depth_of_field": "f/1.8 to f/2.2, keeping the eyes and lips razor sharp while instantly blurring the ears and background.",
"focus": "Critical focus on the eyelashes and iris texture."
},
"negative": {
"content": "No snow, no rain, no wet hair, no masculine jawline, no skin texture, no pores, no heavy contouring, no western makeup style, no sunglasses, no hand near face.",
"style": "No cinematic dramatic shadows (must be flat lit), no warm vintage tones, no painting, no illustration."

“意图”：“在晴朗的天气条件下，利用直接闪光灯摄影，在夜晚创作一张极具理想化、‘抖音美学’风格的年轻女性肖像，以营造高对比度、空灵的视觉效果。”
“框架”： {
"aspect_ratio": "9:16",
“构图”：“极近距离的自拍取景（比标准肖像照更近），裁掉额头顶部，将焦点集中在眼睛和嘴唇上。拍摄对象位于画面中心，目光直视前方。”
"style_mode": "闪光灯摄影、数码网红美学、柔焦写实主义。"
},
“主题”： {
“身份描述”：“一位大约20岁的年轻亚裔女性，拥有高度对称、娃娃般的五官，其特征是‘兔舌’和‘小狗眼’。”
“肌肤”：苍白、冷调的瓷白肤色，几乎没有纹理。肌肤反射闪光灯，呈现出“麻糬”或“玻璃肌”的效果，看起来柔和通透。T区高光突出。
“眼睛”：大而圆的眼睛，外眼角略微下垂（小狗眼）。突出的眼下脂肪纹（眼袋）增添了青春气息。虹膜呈柔和的棕色，直径较大。睫毛采用“漫画”或“偶像”风格：睫毛根根分明，呈垂直的簇状，涂抹睫毛膏，彼此之间留有空隙，而不是浓密的扇形。
“鼻子”：“小巧的鼻子，鼻梁较低，鼻尖小而圆润。光线柔和地弱化了鼻孔的轮廓，使鼻子看起来精致而不突兀。”
“唇部”：心形唇妆，采用渐变唇妆技术。唇部中央是饱满亮泽的草莓粉色，向外晕染至唇线边缘的浅裸色。质地柔软水润。
“头发”： “长长的、丝滑的乌黑直发。没有雪的时候，头发干燥顺滑，微微别在耳后或柔顺地垂在脸颊两侧，在闪光灯下泛着白色的光泽。”
“衣橱”：“低调的款式，暗示着一件时尚休闲的上衣，适合愉快的夜晚穿着。”
},
“环境”： {
“地点”：“都市夜景。”
天气：晴朗、平静、美丽的夜晚。大气洁净，无降水或雾。
“背景”：“深黑色的阴影背景中点缀着远处城市灯光（路灯、霓虹灯）投射出的柔和圆形散景。背景明显比主体暗，从而确保面部成为唯一的焦点。”
},
“灯光”： {
“类型”：“直接闪光灯、前置摄像头闪光灯或高强度屏幕闪光灯。”
“品质”：“硬朗但柔和的光线，使面部轮廓更加平滑，消除眼下和鼻下的阴影。这营造出一种二维的、插画般的质感，常见于高端社交媒体自拍中。”
“对比度”：“明亮的脸部与漆黑的环境形成鲜明对比。”
“眼神光”：“闪光灯照射到瞳孔中心时，形成的一个清晰、细小的点状反射光。”
},
“相机”： {
"sensor_format": "智能手机主传感器模拟。",
“镜头”：“24mm广角镜头。这种焦距会略微放大眼睛，缩小鼻子和脸部宽度，从而营造出‘娃娃脸’的比例。”
"aperture_depth_of_field": "f/1.8 至 f/2.2，保持眼睛和嘴唇清晰锐利，同时立即虚化耳朵和背景。"
“焦点”：“重点关注睫毛和虹膜的纹理。”
},
“消极的”： {
“内容”：“没有雪，没有雨，没有湿头发，没有男性化的下巴线条，没有皮肤纹理，没有毛孔，没有浓重的修容，没有西式妆容，没有太阳镜，没有手靠近脸部。”
“风格”：“禁止使用电影般的戏剧性阴影（必须采用平光），禁止使用温暖的复古色调，禁止使用绘画风格，禁止使用插画风格。”
