Character Consistency AI

Character Consistency in AI Images with Nano Banana

Keep the same face, hair, and identity across scenes, outfits, and styles. Use strict preservation prompts so the model changes only the one thing you asked for.

One Character, Multiple Scenes

Use one reference image as the identity anchor, then change one variable at a time. These examples keep the character recognizable while changing lighting, pose, outfit, or scene.

Quick Answer

Character consistency means locking identity cues such as face, hair, expression, and body proportions while changing only one variable at a time. The most reliable workflow is image-to-image with explicit preservation constraints and a single editing objective.

How It Works

Upload a clear photo (good lighting, minimal blur).

Use a strict "preserve identity" prompt template.

Change ONE thing at a time (outfit OR background OR style).

Recipe 02

Apply a style while preserving identity and composition.

Try

Try

Keep the subject EXACTLY the same. ONLY CHANGE the background to [new scene]. Match lighting direction and color temperature. Clean edges, no halos.

Common Issues & Quick Fixes

Face changes unintentionally

Frequently Asked Questions

Why does the face change in Img2Img?

AI models sometimes "beautify" or adjust faces by default. Adding strict constraints like "EXACT same face shape, eyes, nose, mouth, expression" helps preserve identity.

What photos work best for consistency?

Clear portraits with good lighting, sharp focus, and minimal occlusion. Front-facing or 3/4 view works best.

Can I keep the background too?

Yes! Add "Keep background EXACTLY the same" to your prompt when you only want to change the outfit or style.
