# Portrait Bokeh Tool

{% @arcade/embed flowId="8RUKZIXAll2G57qts6uU" url="<https://app.arcade.software/share/8RUKZIXAll2G57qts6uU>" %}

The **Portrait Bokeh** tool in Aperty creates a beautiful background blur effect, simulating the depth of field seen in professional portrait photography. It enhances the subject by softening the background focusing on the person while keeping the portrait visually appealing.

* **Amount**: Controls the intensity of the background blur. Increasing this slider creates a stronger blur effect while lowering it preserves more background detail. Use this to control the separation between the subject and the background.

**Background Section**\
Offers advanced controls to fine-tune the appearance of the blurred background, ensuring it enhances the portrait without distracting from the subject.

* **Brightness**: This slider adjusts the brightness of the background after the blur is applied. Increasing it makes the background lighter while decreasing it darkens the blurred areas. This helps balance the contrast between the subject and background.
* **Highlights Glow**: Enhances the glow of bright areas within the blurred background, making light sources and reflections more prominent. This can create a soft, dreamy effect, especially with lights in the background.
* **Warmth**: Adjusts the background's color temperature. Increasing this value adds warmth (yellow/orange tones), while lowering it cools the background (blue tones). This adjustment helps match the background with the mood and color scheme of the portrait.
* **Depth Correction**: Refines how the blur is applied based on the perceived distance between the subject and the background. Increasing this slider adjusts the depth for a more accurate and natural-looking blur, especially for complex backgrounds.
* **Edge Correction**: Ensures smooth transitions between the subject and the blurred background. Increasing this slider softens the edges around the subject, preventing harsh lines where the blur meets the subject. Lowering it can create sharper separation if desired.

{% hint style="info" %}
For professional-looking portraits, use a moderate Amount of blur to isolate the subject without completely losing background context. Apply Edge Correction to smooth out transitions and fine-tune Brightness and Warmth to harmonize the background with the subject's lighting and skin tones.

## 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://support.aperty.ai/how-to-use-aperty/four-key-tools-categories/creative-tools/portrait-bokeh-tool.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.
