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