## What it does

The clip starts on your photo with a neutral expression. Your eyes crinkle, a smile spreads, and you burst into a big natural laugh with your head tipping back, ending still grinning.

## From our test

Our test used a woman with curly hair in a blue sweater near a window. Her neutral face turns into a wide laugh over the last frames, with her eyes squeezed nearly shut.

## Tips for the best photo

- Use a close-up of your face, looking at the camera.
- A neutral or lightly smiling expression gives the laugh more room to grow.
- Good, even light helps the expression read.

## Ideas for using it

- A friend sends a happy-birthday laugh to a group chat.
- A creator uses it as a reaction clip.
- A team lead creates a fun greeting for a morale post.
