Portrait consistency is a systems problem

Teams often get inconsistent portrait outputs because prompts are written ad hoc by different people.

The solution is a style system, not one-off prompt tweaks.

Style system components

• Lighting profile
• Background profile
• Color grade profile
• Framing profile
• Subject constraints

Baseline prompt structure

Generate a professional portrait in brand-consistent style.
Keep identity and facial geometry unchanged.
Use soft key light with controlled rim highlights.
Use clean background with brand-compatible tones.
No text, no logo overlays, no watermark.

Versioning strategy

Maintain style versions:

• portrait-v1-neutral
• portrait-v1-campaign
• portrait-v2-dark-accent

This makes approvals and rollbacks straightforward.

QA checks

• Skin tone realism
• Eye detail consistency
• Background cleanliness
• Cross-channel crop safety

Compliance reminder

Never use portrait edits to impersonate real individuals or misrepresent identity.
