Stable Diffusion is a powerful AI image generator that allows users to create detailed landscape images simply by providing text prompts. However, getting high-quality results consistently can be challenging. That’s where negative prompts come in handy.
Negative prompts are instructions you can add to your text prompt to tell Stable Diffusion what not to include in the generated image. Using negative prompts gives you more control over the output and helps avoid unwanted elements.
Here are some common issues that negative prompts can help fix in landscape images:
Removing Unwanted Objects
Stable Diffusion may sometimes randomly generate things like buildings, people, or animals in landscape images where you don’t want them.
To avoid this, add negative prompts like:
no people, no buildings, no cars, no boats, no animals
Fixing Image Quality Issues
Landscape images can suffer from quality issues like:
- Blurriness
- Low resolution/detail
- Compression artifacts
- Overexposed or underexposed areas
Fix these by adding:
not blurry, high resolution, high quality, no artifacts, properly exposed
Changing Lighting and Weather
You can guide the lighting and weather in your generated landscape by using negative prompts like:
no rain, no snow, no clouds, no fog, sunny, bright lighting
Conversely, you can prompt for specific conditions by negating their opposites:
no clear skies, no direct sunlight
Improving Realism
Sometimes Stable Diffusion generates landscapes that seem a bit “off”. They may have weird colors, lighting that doesn’t match, objects floating in the air etc.
Fix realism issues with:
realistic, accurate lighting, no floating objects
Note: You still have to provide a descriptive positive prompt for the landscape you want to generate, in addition to using negative prompts.
Crafting Negative Prompts for Landscapes
When creating negative prompts, follow these best practices:
Be Specific
Use concrete nouns instead of broad adjectives:
no trees, no houses
Not:
not manmade, natural
Prioritize Key Elements
Focus on negating unimportant elements first before moving to important ones:
no clouds, no fog, no snow, no rain, sunny
The weather is less important than the landscape itself, so address weather issues first.
Use Multiple Variants
List multiple synonyms to cover all possibilities:
no people, no humans, unpopulated
Modulate Severity
For elements you may want reduced but not eliminated, modulate severity:
fewer clouds:(1.2)
Higher numbers indicate more emphasis on reduction.
Experiment Iteratively
Start with a few common negative prompts, generate samples, then adjust prompts based on results. Rinse and repeat.
