# Bria Relight - 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 | - |
| `light_type` | Lighting atmosphere to apply. | COMBO | Yes | `"midday"` `"blue hour light"` `"low-angle sunlight"` `"sunrise light"` `"spotlight on subject"` `"overcast light"` `"soft overcast daylight lighting"` `"cloud-filtered lighting"` `"fog-diffused lighting"` `"moonlight lighting"` `"starlight nighttime"` `"soft bokeh lighting"` `"harsh studio lighting"` |
| `light_direction` | Where the light comes from. Hard-light atmospheres such as midday, spotlight on subject and harsh studio lighting react to it the most. | COMBO | Yes | `"front"` `"side"` `"bottom"` `"top-down"` |
| `moderation` | Moderation settings. Select `"true"` to reveal the moderation options, or `"false"` to run without them. | DYNAMIC\_COMBO | Yes | `"false"` `"true"` |

### 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` `false` |
| `visual_output_moderation` | Enables content moderation on the generated output image. Default: false. | BOOLEAN | No | `true` `false` |

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

## Outputs

| Output Name | Description | Data Type |
| - | - | - |
| `image` | The relit image returned by Bria. | IMAGE |
| `structured_prompt` | Structured description of the edited image, for a follow-up edit with Bria FIBO Image Edit. | STRING |
