# Anna — Cinematic Virtual Actress

![Anna — Cinematic Virtual Actress](examples/02_EXPRESSIONS/EXP_00_NEUTRAL.png)
**Anna** is an original fictional female character created for cinematic storytelling, virtual production, concept art and consistent character generation.

This Character LoRA was trained for **[Tongyi-MAI/Z-Image-Turbo](https://huggingface.co/Tongyi-MAI/Z-Image-Turbo)**. It is designed to preserve Anna's recognizable facial identity across different camera angles, expressions, hairstyles, clothes, lighting conditions, locations and historical or science-fiction settings.

Anna has a mature Mediterranean appearance, very dark brown hair, gray-green hazel eyes and a calm, intelligent and self-assured cinematic presence. She is intended to function as a reusable virtual actress rather than as a single fixed portrait.

> Anna is an original fictional character and is not intended to represent any real person.

## Technical information

| Item | Value |
|---|---|
| Public name | Anna — Cinematic Virtual Actress |
| Type | Character LoRA |
| Base model | Z-Image Turbo |
| Trigger word | `ana_biosyn` |
| Recommended initial strength | `0.8–1.0` — still being evaluated |
| Steps | 8–9 |
| Guidance | 1 |
| Training resolution | 512–768 |
| Recommended generation resolution | 768–1024 |
| Format | Safetensors BF16 |
| Tested interface | ComfyUI |
| Character type | Original fictional character |

> Note: the tested ComfyUI workflow uses Guidance 1.  
> When using the official Diffusers `ZImagePipeline`, use `guidance_scale=0.0`.

## What this LoRA does

The LoRA adds Anna's identity to Z-Image Turbo. It can be used to generate:

- close-up and medium cinematic portraits;
- three-quarter and profile views;
- full-body compositions;
- different facial expressions and emotions;
- contemporary, historical and science-fiction costumes;
- natural daylight, studio lighting and dramatic cinematic lighting;
- recurring images of the same character for storyboards, films and visual narratives.

The LoRA controls the **character identity**. The surrounding scene, clothing, pose, expression, camera and lighting should still be described in the prompt.

## Installation in ComfyUI

1. Download `ANA_IDENTITY_ZIMAGE_V1.safetensors`.
2. Copy it into:

   ```text
   ComfyUI/models/loras/
   ```

3. Restart ComfyUI, or refresh its model list.
4. Load **Z-Image Turbo** as the base model.
5. Add a LoRA Loader node and select `ANA_IDENTITY_ZIMAGE_V1.safetensors`.
6. Start with a LoRA strength between `0.8` and `1.0`.
7. Include the trigger `ana_biosyn` near the beginning of the prompt.

## Recommended settings

| Setting | Recommended value |
|---|---|
| Base model | `Tongyi-MAI/Z-Image-Turbo` |
| LoRA strength | `0.8–1.0` |
| Sampling steps | `8–9` |
| Guidance | `1` |
| Sampler | FlowMatch-compatible Z-Image workflow |
| Resolution | 768–1024 pixels on the principal dimension |

These are starting values rather than absolute requirements. A lower strength can give the prompt more freedom, while a higher strength can reinforce Anna's identity.

## Trigger word

```text
ana_biosyn
```

For best identity retention, use `ana_biosyn woman` close to the beginning of the prompt.

## Example prompts

### Natural close-up

```text
close-up cinematic photograph of ana_biosyn woman, calm neutral expression,
direct eye contact, loose dark brown hair, pale blue cotton shirt, modern apartment,
soft window daylight, realistic skin texture, shallow depth of field,
natural cinematic color grading
```

### Science-fiction scene

```text
ana_biosyn woman inside a vast futuristic archive, intelligent and determined gaze,
dark green technical uniform, translucent data displays, restrained cinematic lighting,
subtle atmospheric haze, realistic skin, highly detailed science-fiction film still
```

### Historical character

```text
ana_biosyn woman as a nineteenth-century scientific explorer, chest-up portrait,
authentic period clothing, leather field notebook, soft natural window light,
realistic skin texture, cinematic historical drama
```

### Emotional scene

```text
cinematic portrait of ana_biosyn woman, restrained sadness, moist gray-green eyes,
subtle natural tears, windswept dark hair, overcast coastal landscape,
realistic emotional expression, dramatic film still
```

## Prompting advice

- Put `ana_biosyn woman` near the beginning of the prompt.
- Describe the desired framing explicitly: `close-up`, `chest-up`, `three-quarter view`, `profile` or `full-body`.
- Describe expression, clothing, lighting and location separately.
- If the identity becomes too dominant or the pose too rigid, reduce the LoRA strength.
- If facial identity becomes too weak, move the trigger earlier and slightly increase the strength.
- For comparisons, keep the same prompt and seed while changing only the LoRA strength.

## Current limitations

- Identity consistency can vary in very distant full-body shots.
- Extreme camera angles, heavy facial occlusion or highly stylized rendering may reduce resemblance.
- Complex scenes containing several similar female characters can cause identity mixing.
- Recommended strength is still being evaluated and may be refined in a later version.
- Results depend on the exact ComfyUI Z-Image Turbo workflow and its model versions.

Only the `.safetensors` file is required for inference. Training caches, optimizer states and source datasets are not required.

## Intended use

This LoRA is intended for lawful creative uses including cinematic previsualization, original fiction, storyboards, concept art, virtual production and experimentation with consistent fictional characters.

Users are responsible for the images they generate and for complying with applicable laws, platform rules and the license of the base model. Do not use the model to impersonate a real person or to create misleading representations presented as authentic events.
