How to Keep Your Face the Same in AI Photos
The secrets of identity-preservation when writing AI photo prompts for ChatGPT and Gemini.
One of the biggest frustrations when using AI to generate photos is that the AI often changes your face, making you look like a generic model. Identity preservation is the key to a good AI photo.
Use the Right Keywords
Your prompt must explicitly command the AI to lock the facial features. Phrases like "Preserve the subject's recognizable facial identity, facial proportions, natural skin tone, age range, hairline, and defining features" help constrain the AI from overwriting your face.
Provide a Good Source Photo
The AI can only work with what it sees. Upload a well-lit, front-facing photo without heavy shadows, sunglasses, or extreme expressions. A neutral, passport-style photo often yields the best results when blending into historical scenes.
