# High Fidelity Mode

<details>

<summary><strong>Overview</strong></summary>

High Fidelity Mode is designed to sharpen and restore images that are blurry, pixelated, or compressed.\
Unlike other modes, it does **not add new textures or artistic reinterpretation**.\
Its purpose is to clean and clarify what’s already in the image faithfully.

Ideal for real-world photos, especially:

* Low-quality smartphone shots
* Scanned documents or printed material

The model enhances edge clarity, local contrast, and texture definition without introducing new elements.\
This makes it one of the safest modes for preserving identity and photographic integrity.

⚠️ **Not suitable for creative tasks or illustration enhancement.**

<summary><strong>Key Adjustable Settings</strong></summary>

* **Face Recovery (toggle)**\
  This option automatically detects human faces and sharpens them:

  * Restores key facial features (eyes, lips, eyebrows, etc.)
  * Preserves facial identity — it does not substitute faces
  * Ideal for old group photos or low-res portraits

* **Preset**\
  High Fidelity uses minimal or automatic presets.\
  The model dynamically adjusts itself based on the photo type.\
  It is always focused on realism and subtle improvement — not style.
