“黑暗教父”结构化肖像
一个高度详细的结构化提示词，用于将参考图像转换为具有严苛顶光和极致明暗对照法（Chiaroscuro）的老年“教父”风格领袖形象。
[GPT-image2 Structural Prompt: {argument name="主题" default="The Dark Godfather"}]
### 1. Identity Transformation (核心人像迁移)
- Base Identity: Take the facial structure from [Reference Image].
- Modifications: Age the face by {argument name="年龄增加" default="30 years"}, adding deep-seated wisdom lines and weathered, leathery skin texture. Maintain the stoic, unshakable gaze of a high-status leader.
### 2. Lighting Architecture (顶光与阴影结构 - 关键)
- Light Source: A single, harsh Vertical Top-Lighting (垂直顶光) from directly overhead.
- Shadow Mapping: This lighting must create cavernous shadows in the eye sockets, making the eyes almost invisible in mystery. It should cast a sharp, long shadow under the nose and chin, highlighting the skull's bone structure for a "silent authority" look.
- Style: Extreme Chiaroscuro (明暗对照). 70% of the face must be submerged in absolute velvet blackness.
### 3. Scene & Composition (场景与构图)
- Subject: The man is seated in a classic high-backed black leather chair. He is slowly and rhythmically stroking a {argument name="宠物" default="dark, sleek cat"} on his lap.
- Foreground: Focus on the contrast between the weathered, powerful hand and the soft fur of the cat.
- Background: A pitch-black, minimalist study. Only a faint, out-of-focus silhouette of a mahogany desk is visible.
- Camera: 85mm lens, f/1.8, medium shot, slight low-angle perspective.
### 4. Color & Texture (色彩与质感)
- Palette: Desaturated color grading. Deep tobacco browns, obsidian blacks, and sharp amber highlights (#B08D6A / #1A120B).
- Texture: 35mm film grain, Subsurface Scattering (SSS) for realistic skin highlights, PBR texture mapping (no plastic feel).
### 5. Negative Constraints (负面约束)
- NO smiling, NO looking at the camera directly, NO youthful skin, NO flat lighting, NO bright backgrounds, NO vibrant colors, NO digital smoothness.[GPT-image2 结构化提示词：{argument name="theme" default="The Dark Godfather"}]
### 1. 身份转换
- 基础身份：采用 [Reference Image] 中的面部结构。
- 修改建议：将面部年龄增加 {argument name="age increase" default="30 years"}，增加深邃的智慧纹路和饱经风霜的皮革质感皮肤。保持高位领袖那种坚毅、不可动摇的凝视感。
### 2. 光影架构（核心）
- 光源：来自正上方的单一、严苛的垂直顶光。
- 阴影映射：这种光影必须在眼窝处制造出深邃的阴影，使双眼几乎隐没在神秘之中。在鼻梁和下巴下方投射出锐利、细长的阴影，以突出骨骼结构，营造出一种“沉默的权威感”。
- 风格：极致的明暗对照法（Chiaroscuro）。面部 70% 的区域必须沉浸在绝对的丝绒黑中。
### 3. 场景与构图
- 主体：该男子坐在一把经典的黑色高背皮椅上。他正缓慢且有节奏地抚摸着膝盖上的 {argument name="pet" default="dark, sleek cat"}。
- 前景：聚焦于饱经风霜、充满力量的手部与猫咪柔软皮毛之间的对比。
- 背景：漆黑、极简的书房。仅能隐约看到一张失焦的红木书桌轮廓。
- 摄影：85mm 镜头，f/1.8，中景，轻微的低角度透视。
### 4. 色彩与质感
- 色调：低饱和度调色。深烟草棕色、黑曜石黑以及锐利的琥珀色高光（#B08D6A / #1A120B）。
- 质感：35mm 胶片颗粒感，次表面散射（SSS）以实现逼真的皮肤高光，PBR 纹理映射（避免塑料感）。
### 5. 负面约束
- 禁止微笑，禁止直视镜头，禁止年轻的皮肤，禁止平光，禁止明亮的背景，禁止鲜艳的色彩，禁止数码平滑感。
