what is negative prompt in stable diffusion

A negative prompt in Stable Diffusion is a parameter that tells the model what to exclude from the images it generates. Negative prompts are a powerful tool that can help you create more precise and controlled images. 

Here are some examples of how you can use negative prompts: 

• Remove unwanted elementsTo avoid generating black and white images, you can use the negative prompt “black & white” or “monochrome”. 
• Fix image abnormalitiesTo improve the quality and body proportions of a portrait, you can use the negative prompt “disfigured, cartoon, blurry, nude”. 
• Remove visual featuresTo remove moss from a forest image, you can use the negative prompt “moss”. 
• Change lightingTo remove fog and make an image look sharper, you can use the negative prompt “darkness, fog”.
