[Stable Diffusion] 상황 별 Negative prompt

 Stable Diffusion 모델에서 좋은 Negative prompts를 사용하면 이상한 이미지가 생성되는 것을 막을 수 있다.

요즘 모델들은 negative prompt 없이도 좋은 이미지를 생성하지만 더욱 더 정교한 이미지를 위해 negative prompt가 필요한 경우가 있다.

 

Stable Diffusion은 text-to-image 모델이며 텍스트를 기반으로 이미지를 생성하는 모델이다.

 

Stable Diffusion을 사용하여 이미지를 만들려면 Negative prompts를 포함한 특정 설정을 이해해야 한다. 이 글에서는 Stable Diffusion에서 상황 별로 추천하는 Negative prompts와 지정된 Prompts 설정이 이미지에 어떤 영향을 미치는 지  예시로 보여준다.

 

해당 Negative prompts를 그대로 사용해도 좋지만 출력하고자 하는 이미지에 따라 조절할 필요가 있다.
