# Enhance face details

Enhancing face details is needed when image is rather small or is heavily distorted with noise, compression artefacts or is blurred.

Face enhancement can be done when adding "face\_enhance" option to enhancements.

Type of the face enhancement can be selected by setting **face\_enhance\_parameters:type** parameter

```
"enhancements": ["face_enhance"],
"face_enhance_parameters": {
    "type": "beautify-real",
    "level": 0.8,
    "smoothing_level": 0.1
}
```

| Parameter       | Description                                                                   |
| --------------- | ----------------------------------------------------------------------------- |
| type            | Face enhancing algorithm, described below.                                    |
| level           | Level of face enhancement, values from 0.0 to 1.0. Default is 1.0 - 100%      |
| smothing\_level | Additional skin smoothing filter, values from 0.0 to 1.0. Default is 0.0 - 0% |

| type          | description                                                                                                                                                    |
| ------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| beautify-real | Enhances face in 2048x2048 resolution, suitable for higher resolution photos effect - real looking skin, no compression/diffusion artifacts. **Default value** |
| beautify      | Enhances face in 512x512 resolution, suitable for beautify effect - smooth skin, no visible artifacts, low resolution though.                                  |

Let's check the examples. Type beautify.
