# BriaRelight - ComfyUI Built-in Node Documentation

> This node changes the lighting atmosphere and direction of an image using Bria.

This node changes the lighting atmosphere and direction of an image using Bria. The image is re-rendered by Bria, so the result is not pixel-aligned with the input; the whole frame is regenerated at about 1 megapixel.

## Inputs

### Common Inputs

| Parameter         | Description                                                                                                                             | Data Type      | Required | Range                                                                                                                                                                                                                                                                                                                                                                      |

| `image`           | The image whose lighting is changed. Any alpha channel is dropped before the image is uploaded.                                         | IMAGE          | Yes      | -                                                                                                                                                                                                                                                                                                                                                                          |

### Moderation Inputs

These options appear when `moderation` is set to `"true"`.

| Parameter                  | Description                                                               | Data Type | Required | Range               |
| -------------------------- | ------------------------------------------------------------------------- | --------- | -------- | ------------------- |
| `visual_input_moderation`  | Enables content moderation on the input image. Default: false.            | BOOLEAN   | No       | `true`<br />`false` |
| `visual_output_moderation` | Enables content moderation on the generated output image. Default: false. | BOOLEAN   | No       | `true`<br />`false` |

Note: Bria re-renders the whole frame at about 1 megapixel, so the result is not pixel-aligned with the input.
