## What it does

The clip begins with your product barely visible in deep shadow. A narrow beam of light passes across it, making the edges and finish flash as it goes, and the product is fully lit and gleaming by the end.

## From our test

We used a gold watch with a black dial on dark velvet, and the middle frame drops almost to black before the light returns along the bracelet links. It took about 2 minutes.

## Tips for the best photo

- Shoot the product on a dark background like black fabric or slate so the sweep has contrast to work with.
- Shiny or metallic finishes, such as watches, rings or car paint, catch the beam best.
- Avoid photos with bright light already spilling everywhere, since the effect needs to start from darkness.

## Ideas for using it

- A watchmaker posting a moody teaser before a new model goes on sale.
- A jeweler showing off the polish on a ring for an anniversary sale.
- A car detailer showing the finish on a freshly coated hood.

## FAQ

### Why does the clip go almost completely dark at one point?

That is part of the effect. The product dips into shadow so the light passing over it has more impact.

### Does it work on matte products?

It works, but the highlights are softer. Glossy and metal surfaces show the moving light much more clearly.

### Do I need to write a prompt for Light Sweep?

No. Light Sweep 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 Light Sweep 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 Light Sweep on any product?

Most physical products work: bottles, cosmetics, shoes, gadgets, food and packaging. A clean, well-lit photo with the whole product in frame keeps the shape and label faithful.
