- Add constraints to information consistency and high quality. Specify issues like:
- Framing (“large shot” or “portrait”)
- Element stage (“excessive element, sharp focus”)
- Realism (“photorealistic” or “stylized illustration”)
- If outcomes are too busy, take away adjectives as a substitute of including extra.
- Keep away from adverse prompting — follow prompting what’s desired.
