Best source photos
Nearly-neutral or soft expression, front-facing, sharp mouth region, even light on the face. That’s the sweet spot for an AI smile filter.
- Avoid mid-speech frames and extreme grimaces.
- Avoid heavy shadow across the mouth.
- Avoid group shots if you only need one person smiling.
Set a realistic smile goal
Aim for friendly closed or lightly open smile first. Huge toothy grins from tightly closed mouths invent teeth and often look wrong.
Tip: If you need a big smile for an ad, start from a photo that already has a slight mouth opening—conversion is easier.
10-second authenticity QA
After generation, check:
- Teeth (if any) match lighting and don’t look pasted.
- Cheek softens a bit—mouth-only changes look fake.
- Eyes still look like you (no random age shift).
- Crop and face size unchanged vs original.
Fix path when it’s uncanny
Change inputs, not luck:
- Use a more frontal portrait
- Choose a softer original expression
- Brighten face lighting (reshoot or pick another frame)
- Accept a subtler smile for professional use
Profile publishing tip
Keep your other photos in a similar expression family. One hyper-smiling AI frame next to five stern originals makes the smile look synthetic even if the pixels are good.
