## What it does

You begin with a calm, neutral look into the camera. Your eyes brighten, the corners of your mouth lift and the clip ends on a wide, real smile with a soft laugh.

## From our test

We used a bearded man in a white tee, and his straight face slowly warmed into a wide smile showing his teeth. Only his expression and a little head movement changed, not his clothes or background.

## Tips for the best photo

- Use a front facing portrait with a neutral expression, since the smile builds from there.
- Keep your face close and well lit, with no sunglasses.
- Avoid photos where you are already smiling, which leaves less change to show.

## Ideas for using it

- A profile video for a LinkedIn or team page that warms up a serious headshot.
- A memorial or tribute clip that adds gentle life to a treasured portrait.
- A dating profile intro that shows a friendly side.

## FAQ

### Will it change my face?

The face stays yours, and only the expression changes, with natural head movement.

### Can I use a photo that already has a smile?

You can, but a neutral starting photo shows the change the best.

### Do I need to write a prompt for Big Smile?

No. Big Smile is a ready-made effect: upload a photo and press Generate. The directions for the motion, camera and lighting are already built in.

### How long is the Big Smile video, and how long does it take?

Every effect makes a 5 second HD video that matches the shape of your photo, portrait or landscape. Most are ready in one to three minutes, and you can leave the page while it renders.

### Does the video have sound?

Yes. Each clip comes with matching ambient sound effects. It does not add music, so you can lay your own track over it in any editor.

### Can I use a photo of someone else?

Only photos of adults, of yourself or of people who agreed to it. Every upload goes through the same safety checks as the rest of PixelDojo.
