# Strong

### Model Overview

**Denoise Strong** targets medium-to-high noise levels from very low-light or high-ISO captures, balancing stronger noise reduction with careful detail retention.

### Key Capabilities

* Designed for images shot in very low light
* Retains more detail than Extreme while reducing heavy noise
* For non-RAW images when Normal does not sufficiently clean the image

### Getting Started

**Endpoint**

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

<details>

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

* `face_enhancement` — boolean
  * Leverages our face recovery model to enhance faces.
* `face_enhancement_strength` — decimal between 0 and 1 *(required if `face_enhancement=true`)*
  * Sets the strength of the face recovery.
* `face_enhancement_creativity` — decimal between 0 and 1 *(required if `face_enhancement=true`)*
  * Choose realistic or creative face recovery.
* `subject_detection` — `"foreground"`, `"background"`, or `"all"`
  * Choose where enhancements are applied.
* `strength` — decimal between 0.01 and 1
  * Reduces noise in the image. Too high can remove detail and slightly blur the image.
* `minor_deblur` — decimal between 0.01 and 1
  * Slightly sharpens the image. Counteracts softness caused by noise reduction.
* `original_detail` — decimal between 0 and 1
  * Return texture and fine details lost during noise reduction. Start at low values and slowly increase.
* `denoise_strength` — decimal between 0 and 1, default 0.5
  * Sets the strength of the denoise.
* `sharpen_strength` — decimal between 0 and 1, default 0.5
  * Sets the strength of the sharpening.
* `opacity` — decimal between 0 and 1, default 1.0
  * Adjust strength of opacity.

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.

**Model-Specific Parameters**

* No parameters

**Resolution Limits**

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

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developer.topazlabs.com/image-models/denoise/strong.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
