# Portrait

### Model Overview

**Sharpen Portrait** is trained to enhance fine detail in high-resolution images of people, prioritizing natural skin texture and facial structure.

### Key Capabilities

* Optimized for faces and skin detail
* Avoids harsh edges and unnatural texture
* Best suited for portraits and close-up human subjects

### Getting Started

**Endpoint**

* <https://api.topazlabs.com/image/v1/sharpen/async>
  * `model` — `"Portrait"`

<details>

<summary><strong>Endpoint-Specific Parameters</strong></summary>

* `denoise_strength` — decimal between 0 and 1, default 0.5
  * Removes noise from the image.
* `face_enhancement` — boolean
  * Leverages our face recovery model to enhance faces.
* `face_enhancement_strength` — decimal between 0 and 1
  * Sets the strength of the face recovery.
* `face_enhancement_creativity` — decimal between 0 and 1
  * Choose realistic or creative face recovery.
* `subject_detection` — `"All"`, `"Foreground"`, or `"Background"`
  * Choose where enhancements are applied.

These parameters should be appended as key-value fields in the form-data request bodies (i.e. alongside the `model`, `output_height`, and `face_enhancement` etc. fields). Any parameters not explicitly provided are **automatically** configured by our auto-parameter model. Extra parameters provided that are not supported are ignored.

</details>

**Model-Specific Parameters**

* `sharpen_strength` — decimal between 0 and 1, default 0.5
* `opacity` — decimal between 0 and 1, default 1.0

{% hint style="info" %}
When calling `"Wildlife"` or `"Portrait"`, If the user does not specify a value for any of the above parameters, it will automatically calculate the optimal settings for sharpening based on the technical quality of the input (effectively the same as calling `"Auto Sharpen"`).
{% endhint %}

**Resolution Limits**

* `input` — 512 MP
* `output` — 512 MP
