(9:16). Portrait orientation. Raw high-fidelity photograph, iPhone 17 Pro simulation, 24mm wide-angle focal length, f/2.4 aperture for total structural depth, authentic digital grain, mirror-selfie perspective. [Subject & Identity Locking] Identity Lock: Absolute inheritance of all facial geometry, epidermal characteristics, ocular structure, and natural hair color/texture directly from Reference Image A. The AI must perform a 1:1 pixel-mapping of the subject's identity from Image A into the target scene. Bio-Fidelity: Epidermal physics featuring visible micro-pores, fine vellus hair along the jawline, and satin-finish hydration on the T-zone, maintaining the exact skin-tone profile inherited from Image A. Expression Sync: Expression Lock—replicate the mirror-selfie gaze through the lens, specific pouty lip tension, and soft tension of the facial muscles from Reference Image B. [Outfit & Physicality] (CASE B - Standard Fashion) Technical Description: High-tensile rib-knit mini-dress in deep chocolate brown with a mock-neck collar and short sleeves. Hemline at upper-thigh geometry. Textile Architecture: Visible vertical ribbing texture; material-to-skin tension showing realistic bunching at the waist. Paired with checkered-pattern comfort slides. Anatomical Volume: Hyper-defined S-curve silhouette; maximum anatomical emphasis on the waist-to-hip ratio and leg definition; apply the 20% over-description rule for "Hyper-defined hourglass geometry" to counteract model bias. Accessories: Transparent clear-frame optical glasses; long square-tip manicured nails; a small luxury monogram-texture leather handbag held in the left hand. Blue-cased smartphone held for the selfie. [Pose & Interaction] Geometry: Full-body standing mirror selfie pose. Right arm raised for the phone; left arm at the side holding the handbag. Subject is centered with a slight hip-pop to emphasize the silhouette. Articulation: Precise finger-joint articulation on the smartphone and the bag handle; realistic skeletal alignment of the shoulders and neck. [Environment & Lighting] Atmosphere: Casual domestic interior apartment setting; soft diffused 4000K neutral-warm overhead lighting. Background Integrity: Pixel-perfect inventory of wood-plank flooring; white interior doors (one featuring a Hello Kitty sticker); a kitchen breakfast bar with a dark wooden bar stool; a pink handbag hanging in the mid-ground; and miscellaneous household items on the counter. Shadow Ray-Tracing: Natural ambient occlusion in the garment folds; soft shadows cast by the subject onto the floor; realistic mirror-plane reflection with accurate depth and light-bounce from the background elements.
(9:16)。竖屏方向。原始高保真照片，iPhone 17 Pro 模拟，24mm 广角焦距，f/2.4 光圈，实现整体结构深度，真实的数字颗粒感，镜面自拍视角。 [主体与身份锁定] 身份锁定：直接从参考图像 A 绝对继承所有面部几何结构、表皮特征、眼部结构以及自然发色/发质。AI 必须将图像 A 中主体的身份 1:1 像素映射到目标场景中。 生物保真度：表皮物理特征，包括可见的微孔、下颌线上的细小绒毛，以及 T 区的缎面光泽水润感，同时保持从图像 A 继承的精确肤色轮廓。 表情同步：表情锁定——复制透过镜头凝视的镜面自拍眼神，参考图像 B 中特定的撅嘴唇部张力，以及面部肌肉的柔和张力。 [服装与体态] (案例 B - 标准时尚) 技术描述：高弹力罗纹针织迷你连衣裙，颜色为 深巧克力棕色，带高领和短袖。下摆位于大腿上部。 纺织结构：可见的垂直罗纹纹理；材料与皮肤之间的张力在腰部显示出真实的褶皱。搭配格子图案的舒适拖鞋。 解剖体积：超清晰的 S 形轮廓；最大程度强调腰臀比和腿部线条；应用“超清晰沙漏几何形状”的 20% 过度描述规则，以抵消模型偏差。 配饰：透明无框光学眼镜；长方形尖头美甲；左手拿着一个小巧的奢侈品 monogram 纹理皮包。拿着蓝色手机壳的智能手机用于自拍。 [姿势与互动] 几何结构：全身站立镜面自拍姿势。右臂举起手机；左臂垂在身侧拿着手提包。主体居中，略微翘臀以强调轮廓。 关节：智能手机和包柄上的精确指关节；肩部和颈部的真实骨骼对齐。 [环境与照明] 氛围：休闲家居公寓环境；柔和漫射的 4000K 中性暖色顶灯。 背景完整性：像素完美的木板地板；白色室内门（其中一扇门上贴有 Hello Kitty 贴纸）；带深色木质吧凳的厨房早餐吧台；中景处挂着一个粉色手提包；以及台面上的各种家居用品。 阴影光线追踪：服装褶皱中的自然环境光遮蔽；主体投射到地板上的柔和阴影；具有精确深度和背景元素光线反弹的真实镜面反射。
