Question 1

What is a negative prompt and why should I use it?

Accepted Answer

A negative prompt tells the model what to avoid, reducing artifacts like blurry textures, extra fingers, or random text. It improves realism and composition without adding complexity to your main idea.

Question 2

How long should my negative prompt be?

Accepted Answer

Aim for 10–20 precise tokens. Start broad—quality, anatomy, background—then add targeted terms based on the artifacts you see. Overly long lists can dilute the effect.

Question 3

Can negative prompts help achieve a photorealistic style?

Accepted Answer

Yes. Pair positive cues like lens type and lighting with negatives such as “cartoonish, painterly, plastic skin.” This combination nudges the model toward a lifelike result.

Question 4

Why do I still get random text or logos in images?

Accepted Answer

Models can hallucinate typographic shapes. Add “text, caption, watermark, logo, gibberish text” to the negative prompt and reinforce a clean background in the positive prompt.

Question 5

What if negative prompts make my images look too sterile?

Accepted Answer

You may be overconstraining. Remove redundant terms and allow some texture. Reintroduce natural detail in your positive prompt, like “film grain” or “subtle skin pores,” for a balanced look.
