Negative prompts

A negative prompt tells the model what to avoid. It is a separate field from the main prompt and it accepts the same free-text as the positive prompt, with the opposite meaning. Use it sparingly and specifically.

When to reach for it

The negative prompt is a last resort, not a default. Most problems people try to solve with negatives are better solved by being more specific in the positive prompt. If you want no text in the image, don't write "no text" in negative, instead describe what the composition actually contains.

Good candidates for negative prompting:

• The model keeps generating an element you did not ask for and cannot remove by rephrasing.
• You want to suppress a common default: watermarks, subtitles, lens flare, motion blur.
• You want to steer away from a known failure mode: distorted hands, extra fingers, text artifacts.
• A style you want to avoid keeps creeping in (photoreal when you asked for illustration, vice versa).

Which models support it

Negative prompting is supported on:

• Fawna Cinema
• Fawna Motion
• Fawna Muse
• Fawna Spark
• Fawna Illustrate

Not supported on Veo-family tiers (Fawna Film, Fawna Film Turbo, Fawna Film Lite, Fawna Audio), Fawna Drama, or Fawna Compose. The negative field is hidden in the composer when those models are selected.

How to write one

Keep it short. A list of 3 to 8 comma-separated terms. Each term is a noun phrase or a visual attribute. Do not use negation ("not sharp") and do not write full sentences.

watermark, text, subtitles, extra fingers, lens flare,
oversaturated colors, plastic skin

I don't want anything weird looking or messed up or blurry, please
make the hands look normal and not have strange fingers or anything
like that, no ugly stuff, no bad art

Useful starter negatives

Save these as personal presets for different use cases.
