How to Avoid the 'Sticker Effect' When Placing Models on New Backgrounds

Quick answer: A model looks 'stuck on' when the light on them doesn't match the scene. Fix it by matching three things: light direction (shadows fall the same way), light colour (warm sunset vs cool shade), and contact shadows under feet or hands. Ask the AI to relight the subject to the new scene rather than only replacing the background.

Three things your eye checks

Viewers instantly notice if the face is lit from the left while the sun is on the right, if the skin is daylight-white in a candle-lit room, or if feet float without a shadow. Fix those three and composites become believable.

How to do it

1. Choose the new scene first, then note where the light comes from.
2. Ask to 'relight the model to match the scene' with the direction and colour.
3. Ask for contact shadows where the model touches the ground or furniture.
4. Add a little scene colour to the edges of the model (rim light).
5. Check at small size — mismatches are often easier to spot as a thumbnail.

Prompt to copy

Place the model from the reference into the new scene. Relight her to match the scene: warm low sunlight from the right, soft warm bounce on the left side of her face, long shadow falling to the left, contact shadow under her feet. Keep face, outfit and pose identical.

Common mistakes

• Replacing the background without relighting.
• Forgetting contact shadows.
• Mixing a sharp model with a very blurry background.

FAQ

Why do AI composites look fake?

Light direction, colour and shadows don't match the scene.

What is a contact shadow?

The small dark shadow where a person or product touches a surface.

Should I relight or only swap the background?

Relight. A background swap alone causes the sticker effect.

Does this work for products too?

Yes, the same three checks apply.
