# 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 | - |
| `light_type` | Lighting atmosphere to apply. | COMBO | Yes | `"midday"`<br />`"blue hour light"`<br />`"low-angle sunlight"`<br />`"sunrise light"`<br />`"spotlight on subject"`<br />`"overcast light"`<br />`"soft overcast daylight lighting"`<br />`"cloud-filtered lighting"`<br />`"fog-diffused lighting"`<br />`"moonlight lighting"`<br />`"starlight nighttime"`<br />`"soft bokeh lighting"`<br />`"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"`<br />`"side"`<br />`"bottom"`<br />`"top-down"` |
| `moderation` | Moderation settings. Select `"true"` to reveal the moderation options, or `"false"` to run without them. | DYNAMIC\_COMBO | Yes | `"false"`<br />`"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`<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.

## 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 |
