## Prerequisites

This skill requires the `cellcog` skill for SDK setup and API calls.

```bash
clawhub install cellcog
```

**Read the cellcog skill first** for SDK setup. This skill shows you what's possible.

**Quick pattern (v1.0+):**
```python
result = client.create_chat(
    prompt="[your image request]",
    notify_session_key="agent:main:main",
    task_label="image-task",
    chat_mode="agent"
)
```

## What You Can Create

### Photorealistic Image Generation

Create stunning images from text descriptions:

- **Portraits**: "Create a professional headshot with warm studio lighting"
- **Product Shots**: "Generate a hero image for a premium smartwatch on a dark surface"
- **Scenes**: "Create a cozy autumn café interior with morning light"
- **Food Photography**: "Generate an overhead shot of a colorful Buddha bowl"

### Character Consistency

Nano Banana excels at maintaining character identity across multiple images:

- **Character Series**: "Create a tech entrepreneur character, then show them in 4 different scenes"
- **Brand Mascots**: "Design a mascot and generate it in multiple poses and contexts"
- **Story Sequences**: "Create a character and illustrate them across 5 story beats"

### Multi-Image Composition

Blend elements from multiple reference images:

- **Style Fusion**: "Combine the color palette of image A with the composition of image B"
- **Character Placement**: "Place this person into a new environment while preserving their likeness"
- **Product Mockups**: "Put this product into a lifestyle setting"

### Image Editing

Transform and enhance existing images:

- **Style Transfer**: "Transform this photo into a Studio Ghibli illustration"
- **Background Swap**: "Place this product on a clean marble surface"
- **Enhancement**: "Add dramatic lighting and cinematic color grading"
- **Modification**: "Change the season from summer to winter in this landscape"

## Tips for Better Images

1. **Be descriptive**: "Woman in office" → "Confident woman in her 40s, silver blazer, modern glass-walled office, warm afternoon light"

2. **Specify style**: "photorealistic", "digital illustration", "watercolor", "anime"

3. **Describe lighting**: "Soft natural light", "dramatic side lighting", "golden hour glow"

4. **For character consistency**: Describe the character in detail first, then reference "the same character" in subsequent prompts.

5. **Include composition**: "Rule of thirds", "close-up portrait", "wide establishing shot"
