Negative Prompts Explained: Tell AI What to Leave Out

A negative prompt is a separate instruction field where you list what you don't want in the output—blurry, watermark, extra fingers, overexposed, cartoon style. The model actively steers away from these concepts during generation, which is far more reliable than trying to describe their absence in your main prompt.

The most effective negative prompts are specific rather than vague. Instead of 'bad quality,' write 'jpeg artifacts, low resolution, noise, grainy.' For portraits, standard exclusions include 'deformed hands, asymmetrical face, bad anatomy, duplicate.' For product shots, try 'shadow, reflection, busy background, text overlay.' Stack 10–20 terms separated by commas for best results.

On CinderHub, the negative prompt field appears below the main prompt in image and video generation modes. Start with a base template you trust, then add scene-specific exclusions on top. Save your best negative prompt sets as reusable snippets—you'll find the same 15-word block eliminates 80% of common artifacts across completely different subjects.
