- Teeth are visible but not forced (natural amount of show).
- Lighting is even across your face (no harsh shadows on mouth).
- Expression looks authentic (not say cheese forced).

FAQ
Why does my smile look forced in photos?
Common reasons are jaw tension, holding the breath, and smiling only with the mouth. Soft front light and a relaxed face help a lot. The key is engaging your eyes, not just your mouth.
Do I have to show teeth?
No. A small natural smile can look very confident. The best choice depends on your vibe and the photo context. Some people look best with a closed-mouth smile.
What's the fastest way to improve my smile?
Relax your jaw, exhale slightly before the shot, and lift your cheeks gently so the smile reaches your eyes. Think of something that genuinely makes you happy.
Does lighting affect how my smile looks?
Yes. Harsh light creates shadows around the mouth and can make teeth look dull. Soft front light is most flattering and reduces the appearance of imperfections.
Why do some people have naturally photogenic smiles?
Usually it's about relaxation and confidence, not genetics. People who are comfortable being photographed tend to have more natural smiles. Practice and good technique can get you there.
Should I smile with teeth or without?
Try both and see what feels natural. Some people look great with teeth showing, others look more authentic with a closed-mouth smile. There is no universal best smile.
