## ⚙️ Settings Guide

### **Reference Strength Control**

The reference strength determines how closely your generated art follows the reference image:

| Strength | Effect | Best For |
|----------|--------|----------|
| **0.1-0.3** | Loose inspiration, high creativity | Abstract concepts, creative freedom |
| **0.4-0.6** | Balanced style transfer | Most use cases, artistic guidance |
| **0.7-0.9** | Close adherence to reference | Style mimicking, specific looks |

### **Quality vs Speed Settings**

| Setting | Fast (10-15 steps) | Balanced (20-30 steps) | High Quality (40-50 steps) |
|---------|-------------------|------------------------|---------------------------|
| **Time** | 30-60 seconds | 1-2 minutes | 3-5 minutes |
| **Quality** | Good for testing | Recommended | Best results |
| **Use Case** | Quick iterations | Final generation | Professional work |

### **Guidance Scale**

| Scale | Effect | Best For |
|-------|--------|----------|
| **5-10** | More creative, loose interpretation | Artistic freedom, abstract art |
| **10-15** | Balanced prompt following | Most use cases |
| **15-20** | Strict prompt adherence | Precise requirements |

## 🎨 Creative Techniques

### **Effective Reference Selection**

#### ✅ **Good References**
- **Clear artistic style** (paintings, digital art, photography styles)
- **Strong visual identity** (distinctive colors, techniques, moods)
- **Good composition** (well-balanced, not cluttered)
- **High contrast** (clear light/dark areas)

#### ❌ **Challenging References**
- **Cluttered images** with too many elements
- **Low contrast** or very dark/bright images
- **Screenshots** or UI elements
- **Text-heavy** images

### **Prompt Enhancement Tips**

#### **Combine Multiple Styles**
```
Base: "A serene mountain landscape"
+ Style: "oil painting, impressionist"
+ Mood: "golden hour, peaceful"
+ AI Suggestions: "soft brushstrokes, warm colors"
= Enhanced: "A serene mountain landscape, oil painting, impressionist, golden hour, peaceful, soft brushstrokes, warm colors"
```

#### **Layer Your Descriptions**
1. **Subject**: What you want to see
2. **Style**: Artistic technique or medium
3. **Mood**: Emotional atmosphere
4. **Details**: Specific elements or effects

### **Reference Strength Strategies**

#### **Creative Exploration** (Low Strength: 0.2-0.4)
- Use reference for general mood/color inspiration
- Allow AI maximum creative freedom
- Good for abstract or conceptual art

#### **Style Transfer** (Medium Strength: 0.5-0.7)
- Balance between reference and creativity
- Maintain reference style while changing content
- Most versatile approach

#### **Style Mimicking** (High Strength: 0.7-0.9)
- Close adherence to reference technique
- Minimal creative deviation
- Good for specific artistic styles

## 📁 Output Management

### **File Naming Convention**

Generated files follow a comprehensive naming pattern:
```
{prompt}_{style}_{mood}_{timestamp}_seed{number}_{REFIMG|NOREFIMG}_v{variation}.png
```

**Example:**
```
magical_forest_fantasy_mystical_20250701_143022_seed12345_REFIMG_v1.png
```

### **Metadata Files**

Each image includes a JSON metadata file with:
- Complete generation parameters
- Reference image information
- AI style analysis results
- Reproducibility data

### **Organization Tips**

- **Create project folders** for different art series
- **Use consistent naming** for easy searching
- **Save metadata** for reproducing successful results
- **Export favorites** to separate collections

## 🔧 Troubleshooting

### **Common Issues**

#### **"Failed to load image from URL"**
- ✅ Check URL is a direct image link
- ✅ Try right-clicking image → "Copy image address"
- ✅ Ensure URL ends with .jpg, .png, etc.
- ✅ Test URL in browser first

#### **"Generation taking too long"**
- ✅ Reduce inference steps (try 15-20)
- ✅ Lower image count (try 1-2 images)
- ✅ Check GPU memory availability
- ✅ Restart application if needed

#### **"Poor quality results"**
- ✅ Increase inference steps (try 30-40)
- ✅ Adjust reference strength
- ✅ Improve prompt specificity
- ✅ Try different reference images

#### **"Out of memory errors"**
- ✅ Enable memory optimizations in settings
- ✅ Reduce batch size to 1 image
- ✅ Close other applications
- ✅ Use CPU mode if necessary

### **Performance Optimization**

#### **For Better Speed**
- Use GPU if available
- Enable memory optimizations
- Start with lower inference steps
- Generate fewer images per batch

#### **For Better Quality**
- Use high-resolution reference images
- Increase inference steps (30-50)
- Fine-tune reference strength
- Use descriptive, specific prompts

## 🎯 Best Practices
