年轻医生的超高保真皮肤纹理肖像

（4:5 垂直构图）。一张使用 iPhone 15 Pro Max（24 毫米镜头）在采光极佳的豪华诊所内拍摄的原始超高分辨率肖像照。

主体：一位年轻女医生（20 岁出头）。
*   皮肤质感（升级版）：阳光从侧面照射在她的脸上。我们可以看到“高保真皮肤纹理”：鼻部和脸颊上有清晰可见的毛孔，下颌线上有被阳光照亮的细小“桃色绒毛”（毳毛），T 区和额头有逼真的油光。皮肤不是哑光的；它看起来像水润、有生命的真人皮肤。
*   头发：“栗棕色”头发。发丝根根分明，被逆光照亮，形成自然的光晕。一些发丝翘起（静电），打破了完美的轮廓。
*   表情：她靠在玻璃上，真诚地微笑着（眼角有细纹，露出淡淡的鱼尾纹），这证明这是一个真实的表情，而不是伪装。

服装（材质对比）：
*   白色实验服：我们可以看到棉斜纹布厚实的编织纹理。在她弯曲的手肘处有明显的折痕。
*   红色丝质文胸，带黑色蕾丝边。
*   金色项链：在阳光下闪烁着明亮的光泽（镜面高光）。

环境与光线：
*   光线：“硬朗的定向日光”。阳光明亮而清晰。它在她的颧骨上投射出睫毛清晰的阴影，并在她所靠的玻璃上投射出她身体的阴影。
*   背景（锐利）：一个现代化的玻璃墙诊所。我们可以看到房间的倒影映在她所靠的玻璃上。背景中一株白色兰花清晰可见。图像清晰，没有人工平滑处理。

**Original English:**
(Vertical 4:5 aspect ratio). A raw, ultra-high-resolution portrait taken with an iPhone 15 Pro Max (24mm lens) in a luxury day-lit clinic.

Subject: A young female doctor (early 20s).
*   Skin Physics (The Upgrade): The direct sunlight hits her face from the side. We can see "High-Fidelity Skin Texture": distinct pores on her nose and cheeks, fine "peach fuzz" (vellus hair) on her jawline backlit by the sun, and a realistic oily sheen on her T-zone and forehead. It is NOT matte; it looks like hydrated, living human skin.
*   Hair: "Chestnut Brown" hair. Individual strands are visible and backlit, creating a natural halo. Some flyaways stick up (static), breaking the perfect silhouette.
*   Expression: She leans against the glass, smiling genuinely (eyes crinkling, showing crow's feet hints) which proves it's a real expression, not a mask.

Outfit (Material Contrast):
*   White Lab Coat: We see the heavy weave of the cotton drill fabric. It has sharp creases at the elbow where her arm is bent.
*   Red silk bra with black lace trim.
*   Gold Necklace: Glints brightly (specular highlight) in the sun.

Environment & Lighting:
*   Lighting: "Hard Directional Daylight". The sun is bright and crisp. It creates a defined shadow of her eyelashes on her cheekbones and a shadow of her body on the glass she is leaning against.
*   Background (SHARP): A modern glass-walled clinic. We see reflections of the room on the glass she is leaning against. A white orchid is sharp in the background. The image is crisp, with no artificial smoothing.
