## Source File
- [[raw/AI/Nano Banana 提示词框架.md]]
## Summary
- 核心主题Nano Banana 图像生成模型的系统化 Prompt 框架,提供物件和人物两类结构化描述模板
- 问题域:用户不知道如何结构化地描述画面元素,导致生成结果不稳定或不精确
- 方法/机制:将图像描述分解为 shot/subject/environment/lighting/camera/color_grade/style/quality/negatives 等字段,填入 JSON 模板
- 结论/价值:结构化 Prompt 是 Nano Banana 生成高质量图像的关键,比自由文本描述准确率高得多
## Key Claims
- **物件描述框架**shot + subject(item/materials/details/condition) + environment + lighting + camera(focal_length/aperture/angle) + color_grade + style + quality + negatives
- **人物描述框架**shot + subject(age/gender/race/build/clothing/hair/facial expression) + environment + lighting + camera + style
- **核心字段**shot景别、negatives负向提示词用于排除不需要的元素、camera镜头参数
- Nano Banana 的差异化优势文本渲染精准文字植入图像、4K 分辨率、角色一致性
