How to Smile Naturally for Photos: 4 Useful Tips

While editing your smile is a great option, many of us want to try to get that perfect smile organically the first time around. If that sounds like you, read on for five tips to get a naturally beautiful smile.

How to smile naturally for photos

1. Smile With Your Eyes

Earlier, we mentioned that it takes 10 muscles to smile, and some of those are actually located higher up on your face, near your eyes.

You’ve probably heard people say smile with your eyes or smile, which refers to the practice of opening your eyes wide and focusing them intently on your target. That’s usually a camera, but it may also be a person.

2. Relax Your Face Muscles

We previously mentioned using your facial muscles to smile but in some cases, you actually want to relax those muscles.

Forcing a smile can look unnatural, so instead, try softening the muscles around your mouth to look more relaxed and effortless.

3. Don’t Focus on the Camera

What, don’t look at the camera?! We know, it sounds silly. But to get that great natural smile, you actually want to vary the place that you’re looking at.

Distract yourself by looking around in different directions before the big moment, as this will produce a more natural and relaxed smile. After all, your best photogenic smile is one that looks authentic and real.

4. Be Confident

Lastly, be confident when you smile! The camera or the person you’re talking to can tell when you aren’t confident or genuine with your facial expression. Instead, use your self-confidence to make your smile the best it can be.
