## Definition
负向提示词Negative Prompting——通过明确指定不想要的内容元素主动排除 AI 生成图像中的干扰元素和常见缺陷,提升生成结果的可控性和专业度。
## Mechanism
在支持负向提示词的 AI 平台Midjourney、Stable Diffusion用户通过专门的语法`--no``negative_weights``NOT` 等)指定需要排除的元素。
## Common Negative Prompt Categories
- **图像缺陷**blurry、noise、grain、artifact、distortion、overexposed、underexposed
- **不想要的对象**watermark、text、logo、signature、frame、border
- **构图元素**background clutter、distracting elements、unwanted objects
- **质量相关**low quality、jpeg artifacts、compression artifacts
- **风格相关**cartoonish当需要写实风格时、oversaturated、overprocessed
## Best Practices
- 针对性而非泛化:只排除确实不想要的特定元素,不过度使用
- 与正向提示词协同:负向提示词补充而非替代正向提示词
- 平台适配各平台负向提示词语法和支持程度不同Midjourney 的 `--no`、SD 的 negative embeddings
