Negative Prompts: How to Remove Unwanted Elements From AI Images

Most guides focus on what to put in your prompt — but what you exclude is equally important. Negative prompts tell the AI model what you don't want in the image, and learning to use them effectively is one of the fastest ways to improve your AI image quality.

What Are Negative Prompts?

A negative prompt is text that tells the AI model to avoid generating certain content or qualities. If your positive prompt describes what to include, the negative prompt describes what to exclude.

How it works: The AI optimization process steers the generation toward your positive prompt while simultaneously steering away from your negative prompt. The result is an image that matches your positive description while avoiding the elements you've excluded.

Negative prompts are supported in most AI image generators, including Lensgo.ai's advanced generation settings.

Universal Negative Prompts for Quality

These negative prompts improve almost every generation:

blurry, out of focus, low quality, low resolution, jpeg artifacts, compression artifacts,
grainy, noisy, overexposed, underexposed, washed out, oversaturated, desaturated,
watermark, signature, text overlay, border, frame, duplicate, extra limbs

This catch-all eliminates the most common AI quality issues: blur, artifacts, exposure problems, and the unwanted extras that sometimes appear.

Portrait-Specific Negative Prompts

Portraits have specific artifacts that benefit from targeted exclusion:

deformed, disfigured, mutated, extra fingers, missing fingers, too many fingers,
fused fingers, long neck, bad anatomy, disproportionate, bad proportions,
ugly, bad face, wrong face, clone face, bad eyes, crossed eyes,
floating limbs, disconnected limbs, plastic skin, airbrushed,
over-smoothed skin, wax figure

The "hand problem" in AI specifically warrants: extra fingers, missing fingers, fused fingers, distorted hands, unnatural hand poses

Landscape and Nature Negative Prompts

people, human, crowds, tourist, man-made structures, power lines,
telephone poles, cars, urban, city, buildings, text, signs,
overprocessed, oversaturated, HDR effect, fake looking, CGI, 3D render

For travel and landscape content, excluding people and urban elements keeps the focus on the natural scene.

Style-Specific Negative Prompts

For photorealism (most important):

cartoon, anime, illustration, painting, drawing, sketch, artistic, stylized,
CGI, 3D render, digital art, cinematic grade, cinematic color

Excluding artistic styles pushes the generation toward photographic reality.

For clean product photography:

people, hands, background clutter, busy background, other products,
distracting elements, shadows, harsh lighting, unflattering angle

How to Structure Negative Prompts Effectively

Prioritize by impact: Put your most important exclusions first. AI systems typically give higher weight to earlier terms.

Be specific: "bad hands" is less effective than "extra fingers, missing fingers, fused fingers, distorted hand anatomy."

Avoid contradictions: Don't put the same concept in both positive and negative prompts. If you want "soft light," don't also negative prompt "soft."

Start with quality universals: Begin with the quality improvement negatives (blurry, low quality, artifacts) before adding content-specific exclusions.

Build a library: Save your most effective negative prompt combinations for different use cases. Your universal quality negative prompt and your portrait-specific negative prompt can be reused across hundreds of generations.

Negative Prompt Templates

General photography:

NEGATIVE: blurry, low quality, artifacts, watermark, text, bad anatomy, extra limbs, deformed, ugly, poorly drawn

Portrait photography:

NEGATIVE: blurry, deformed face, extra fingers, distorted hands, bad anatomy, plastic skin, airbrushed, oversaturated, text, watermark

Travel/landscape:

NEGATIVE: people, urban, power lines, signs, CGI, 3D render, cartoon, oversaturated, HDR, low quality

Product photography:

NEGATIVE: people, hands, background clutter, text, watermark, blurry, low quality, distracting elements, shadows

Negative prompts are one of the fastest ways to move from mediocre to excellent AI generations. Start with the universal quality template and add use-case-specific exclusions as you identify what's showing up in your generations that you don't want.
