Negative Prompts
Use negative prompts to suppress common defects, artifacts, and unwanted objects—without fighting your main brief.
What negative prompts are for
They answer: “Assume I never want X unless I ask.” Typical targets:
- Watermarks, logos, UI overlays
- Extra limbs, mangled hands, duplicated faces
- Blurry faces when you need sharp portraits
- JPEG artifacts when you need clean edges
Keep negatives specific
Prefer “deformed hands, extra fingers” over “bad quality.” The latter is vague and can flatten desirable texture.
Avoid contradictions
If your main prompt asks for heavy film grain, a negative of “grain” will fight you.
Order and quantity
Start with 3–7 high-value negatives. Long laundry lists often dilute focus and surprise you with odd side effects.
Pair with positive language
Sometimes a positive clause is better:
- Negative: “no text”
- Positive: “clean background, no typography, no signage”
Google’s image docs call this semantic negative prompting: describe the scene you want (including “empty of X”) rather than only forbidding lists. That tends to produce cleaner composition than long “no …” chains alone. See Gemini API — image generation.
Product-specific features
If the app exposes preset negative packs (portrait, product, typography), start there and customize.
