# Using Virtual Background

Windows, Mac

The **Virtual Background** function provided by PRISM Lens automatically removes the background and adds a desired background image without requiring the user to have a solid chroma key cloth behind them or use a 3D depth camera.

You can use the background images provided by PRISM or select your own favorite image or video files.

***

To use the Virtual Background function, click the Virtual Background icon on the Sidebar.

## Remove Background

You can easily remove the background by clicking the **Remove BG button**.

PRISM Lens automatically detects the person and separates them from the background in real-time. When connected with PRISM Live Studio, the background of the source will appear transparent. For more information about connecting PRISM Live Studio, refer to the following page:&#x20;

## Apply Virtual Background

### Apply PRISM Virtual Background

Alternatively, you can enhance the background by selecting an image from the **PRISM** tab.

Some of these backgrounds include motion effects. If you prefer a static background, you can disable the motion by toggling the **Motion Off** option.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://guide.prismlive.com/lens/guides/features/virtual-background/using-virtual-background.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
