# Natural

### Model Overview

**Sharpen Natural** is designed for texture-sensitive images where realism is prioritized over maximum sharpness, preserving organic surfaces without introducing artifacts.

### Key Capabilities

* Maintains realistic texture and surface detail
* Ideal for subtly soft images requiring restrained enhancement
* Avoids halos, plastic textures, and over-sharpened edges

### Getting Started

**Endpoint**

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

<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**

* `strength` — decimal between 0.01 and 1
* `minor_denoise` — decimal between 0.01 and 1

**Resolution Limits**

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