## 设计指南
|
||
|
|
|
||
|
|
### 🎯 核心设计理念
|
||
|
|
|
||
|
|
这个提示词模板采用**结构化 JSON 格式**，将图片生成的各个维度明确拆分，确保 AI 能够精确理解并生成符合预期的图像。
|
||
|
|
|
||
|
|
### 📚 模块说明
|
||
|
|
|
||
|
|
#### 1. **Subject（主体）** - 核心人物
|
||
|
|
- **description**: 人物的基本定位和动作
|
||
|
|
- **pose**: 具体姿态细节
|
||
|
|
- **expression**: 面部表情和情绪
|
||
|
|
|
||
|
|
> **设计要点**: 从整体到细节，先定义"是谁"，再描述"在做什么"，最后补充"表情如何"
|
||
|
|
|
||
|
|
#### 2. **Clothing（服装）** - 着装细节
|
||
|
|
- **upper_body/lower_body**: 分区域描述
|
||
|
|
- **visibility**: 可见度说明（处理遮挡情况）
|
||
|
|
|
||
|
|
> **设计要点**: 不仅描述服装本身，还要说明可见程度，这对光影和构图很重要
|
||
|
|
|
||
|
|
#### 3. **Hair（发型）** - 发型与光线
|
||
|
|
- **color**: 颜色
|
||
|
|
- **style**: 风格和质感
|
||
|
|
- **lighting_interaction**: 与光线的交互效果
|
||
|
|
|
||
|
|
> **设计要点**: 头发是体现光线效果的关键元素，单独设置光线交互项能显著提升画面质感
|
||
|
|
|
||
|
|
#### 4. **Face（面部）** - 面部特征
|
||
|
|
- **skin_tone**: 肤色和色调
|
||
|
|
- **features**: 五官特点
|
||
|
|
- **makeup**: 化妆程度
|
||
|
|
|
||
|
|
> **设计要点**: 肤色要包含"底色"描述（冷/暖），这影响整体色调
|
||
|
|
|
||
|
|
#### 5. **Accessories（配饰）** - 可选装饰
|
||
|
|
- **visible_items**: 可见的配饰
|
||
|
|
|
||
|
|
> **设计要点**: 即使没有配饰，也应说明"无"，这能避免 AI 随机添加
|
||
|
|
|
||
|
|
#### 6. **Environment（环境）** - 场景设定
|
||
|
|
- **setting**: 整体场景类型
|
||
|
|
- **background_elements**: 背景元素
|
||
|
|
- **foreground_elements**: 前景元素
|
||
|
|
|
||
|
|
> **设计要点**: 前景/背景分离描述，前景元素可以创造景深和叙事层次
|
||
|
|
|
||
|
|
#### 7. **Lighting（光照）** - 光线系统 ⭐ 核心
|
||
|
|
- **source**: 光源位置和类型
|
||
|
|
- **quality**: 光线品质（硬/软、冷/暖）
|
||
|
|
- **effects**: 具体光效（光晕、尘埃、镜头光斑等）
|
||
|
|
|
||
|
|
> **设计要点**: 光照是照片级渲染的灵魂。务必明确：
|
||
|
|
> - 光从哪里来？
|
||
|
|
> - 是什么时间的光？（黄金时段/正午/蓝调时刻）
|
||
|
|
> - 有哪些特殊效果？（体积光、轮廓光、镜头光晕）
|
||
|
|
|
||
|
|
#### 8. **Camera（镜头）** - 摄影技术
|
||
|
|
- **perspective**: 视角和位置
|
||
|
|
- **focus**: 对焦方式（景深）
|
||
|
|
- **lens_character**: 镜头特性（柔焦/颗粒/畸变）
|
||
|
|
|
||
|
|
> **设计要点**: 模拟真实摄影师的思维：
|
||
|
|
> - 我站在哪里拍？
|
||
|
|
> - 焦点在哪里？
|
||
|
|
> - 用什么镜头？（85mm 人像 / 35mm 纪实 / 50mm 标准）
|
||
|
|
|
||
|
|
#### 9. **Style（风格）** - 整体美学
|
||
|
|
- **aesthetic**: 美学关键词
|
||
|
|
- **mood**: 情绪氛围
|
||
|
|
- **visual_reference**: 视觉参考（可引用知名摄影师/画家/电影风格）
|
||
|
|
|
||
|
|
> **设计要点**: 这是"元指令"层，用风格关键词统领全局，如：
|
||
|
|
> - `Cinematic` → 宽画幅、色彩分级
|
||
|
|
> - `Film photography` → 颗粒、色偏
|
||
|
|
> - `Japanese photobook` → 自然、克制、留白
|
||
|
|
|
||
|
|
### 🔧 使用技巧
|
||
|
|
|
||
|
|
#### ✅ 最佳实践
|
||
|
|
1. **从宏观到微观**: 先定义风格和氛围，再填充细节
|
||
|
|
2. **光线优先**: 光照决定 80% 的画面质量，务必详细描述
|
||
|
|
3. **具体化描述**: 避免 "beautiful"、"nice"，用具体特征：
|
||
|
|
- ❌ "beautiful lighting"
|
||
|
|
- ✅ "golden hour sunlight with soft rim lighting"
|
||
|
|
|
||
|
|
4. **视觉参考**: 善用 `visual_reference` 引用已知风格：
|
||
|
|
- "Wong Kar-wai cinematography"（王家卫电影风格）
|
||
|
|
- "Annie Leibovitz portrait"（安妮·莱博维茨人像）
|
||
|
|
- "Wes Anderson symmetry"（韦斯·安德森对称构图）
|
||
|
|
|
||
|
|
#### ⚠️ 常见误区
|
||
|
|
1. **过度堆砌**: 不要在一个字段里塞太多关键词，分散到各模块
|
||
|
|
2. **忽略负面**: 如果某些元素"不要出现"，在对应字段明确说明
|
||
|
|
3. **矛盾指令**: 检查各模块是否协调（如 "sharp focus" 和 "soft bokeh" 的平衡）
|
||
|
|
|
||
|
|
