Learn How to Use Negative Prompts in Stable Diffusion

Stable Diffusion Negative Prompt

Hey there, I'm Jakob Stewart, and today, I’m going to explain how you can use negative prompts to get better results with Stable Diffusion.


If you're looking to refine your images or make sure they come out exactly as you envision, negative prompts are key.


Quick Links:





What is a Negative Prompt in Stable Diffusion?


A negative prompt is a function in Stable Diffusion that lets you specify elements you don't want in your generated images.

It works by guiding the AI away from certain features, making your images more aligned with your vision.


Think of negative prompts as instructions that tell the AI to "Avoid these things." 


This can help fine-tune the output to avoid unwanted aspects like blurry details, extra limbs, or any other elements that might not fit your creative goals.



Using Negative Prompts Effectively


To use a negative prompt, you just need to include it in the settings when you're generating an image. Most Stable Diffusion interfaces have a dedicated spot for this.


For example, if you want to create an image of a serene landscape but don't want any people in it, you can set "people" as a negative prompt.


This will tell the AI to avoid including people in the generated image.

Examples of Negative Prompts in Stable Diffusion


Negative prompts can cover a wide range of scenarios. Here are some common ones you might find helpful:


  • General Quality: words like "blurry," "pixelated," or "low quality" help ensure your images come out sharp and clear.

  • Anatomical Accuracy: terms like "extra limbs," "disfigured," or "poorly drawn face" can help maintain realism in human or animal figures.

  • Aesthetic Choices: using "boring," "dull," or "monochrome" can help keep your images vibrant and visually interesting.


Here’s a negative prompt I use almost every time:

Negative Stable Diffusion Prompts
(deformed iris, deformed pupils, semi-realistic, CGI, 3d, render, sketch, cartoon, drawing, anime, mutated hands and fingers:1.4), (deformed, distorted, disfigured:1.3), poorly drawn, bad anatomy, wrong anatomy, extra limb, missing limb, floating limbs, disconnected limbs, mutation, mutated, ugly, disgusting, amputation


Best Practices for Specific Scenarios


For Portraits: If you're creating a portrait and want a clean, professional look, consider adding prompts like "poor lighting" or "blurry details" to avoid common issues.


For Landscapes: To enhance natural scenes, negative prompts like "artificial colors" or "unnatural shapes" can help keep the image realistic.


For Abstract Art: When creating abstract art, avoid prompts that could add unintended realism, like "detailed anatomy" or "realistic textures."


🚀 Bonus TIP: Finding Parameters


Always check the "Generation data" for images you like on CivitAI. 

It’s where you’ll find details like the prompt, CFG scale, steps, seed, and other key settings. This info helps you really understand how the image was created and what made it work.
