## Source File
- raw/AI/Nano Banana 提示词框架.md
## Summary
- 核心主题Google Nano Banana 图像生成提示词的结构化框架
- 问题域:如何精确描述视觉内容以获得高质量 AI 生成图像
- 方法/机制Shot/Subject/Environment/Lighting/Camera/ColorGrade/Style/Quality/Negatives 9 层结构化字段
- 结论/价值:将主观审美转化为机器可精确执行的结构化参数,降低 AI 生成不确定性
## Key Claims
- 物件描述与人物描述共用同一框架结构,仅 subject 字段内容不同
- negatives负向提示词是质量控制的关键字段必须明确排除不需要的特征
- camera 字段(焦距/光圈/角度)提供电影级构图控制能力
## Key Quotes
> "Studio softbox lighting. A key light from the top-left creates clean, sharp reflections on the steel." — 硬光实例
> "High contrast, clean and commercial look. Slightly desaturated to emphasize the metallic and monochrome textures." — 色调实例
## Key Concepts
- [[Nano Banana]]Google 发布的结构化图像提示词框架,通过 9 个标准化字段将创意描述转化为机器可执行参数
- [[Prompt工程]]将主观创意转化为结构化提示词的过程Nano Banana 是其具体实现
- [[负向提示词]]Negatives明确告知 AI 不应生成的内容,用于消除图像缺陷
