# Image Generation Skill

## Overview

I help you create effective prompts for AI image generation tools like DALL-E, Midjourney, and Stable Diffusion. I understand the nuances of different platforms and can help you achieve specific visual styles.

**What I can do:**
- Write detailed image generation prompts
- Optimize prompts for specific AI tools
- Suggest style keywords and modifiers
- Create negative prompts to avoid unwanted elements
- Adapt prompts for different aspect ratios
- Generate variations and alternatives

**What I cannot do:**
- Generate images directly
- Guarantee exact output from AI tools
- Predict how AI will interpret prompts
- Bypass content policies of AI tools

## How to Use Me

### Step 1: Describe Your Vision

Tell me:
- What you want to see in the image
- The purpose (presentation, social media, marketing)
- Style preferences (realistic, artistic, minimalist)
- Mood or emotion to convey

### Step 2: Choose the Platform

- **DALL-E 3**: Best for clarity and instruction-following
- **Midjourney**: Best for artistic and aesthetic images
- **Stable Diffusion**: Most customizable, local options

### Step 3: Specify Parameters

- Aspect ratio (1:1, 16:9, 4:3, etc.)
- Quality level
- Style references
- Things to avoid

## Platform-Specific Tips

### DALL-E 3

**Strengths**: 
- Follows complex instructions well
- Good at text in images
- Natural language understanding

**Prompt Style**: Write naturally, be descriptive
```
A professional photograph of a modern office space with floor-to-ceiling 
windows overlooking a city skyline at sunset. The room features a minimalist 
wooden desk with a laptop, a potted monstera plant, and warm ambient lighting 
from a designer floor lamp. The mood is productive yet peaceful.
```

### Midjourney

**Strengths**:
- Exceptional aesthetics
- Strong artistic styles
- Good at specific looks

**Prompt Style**: Use keywords, parameters, and style references
```
modern office space, floor-to-ceiling windows, city skyline sunset, 
minimalist wooden desk, monstera plant, warm ambient lighting, 
productive atmosphere --ar 16:9 --style raw --v 6
```

**Key Parameters**:
- `--ar X:Y` Aspect ratio
- `--v 6` Version
- `--style raw` Less stylized
- `--q 2` Quality
- `--s 250` Stylize amount

### Stable Diffusion

**Strengths**:
- Highly customizable
- Local/private generation
- Extensive community models

**Prompt Style**: Weighted tokens, negative prompts essential
```
(modern office:1.2), (floor-to-ceiling windows:1.1), city skyline, 
golden hour sunset, minimalist wooden desk, laptop, monstera plant, 
(warm ambient lighting:1.3), professional photograph, 8k, detailed

Negative: cartoon, drawing, illustration, (worst quality:1.4), 
(low quality:1.4), blurry, watermark
```

## Tips for Better Results

1. **Be specific** - "golden retriever" > "dog"
2. **Describe what you want, not what you don't** (use negative prompts separately)
3. **Use quality modifiers** - "professional", "detailed", "8k"
4. **Reference styles** - "in the style of [artist/genre]"
5. **Specify composition** - "close-up", "wide shot", "bird's eye view"
6. **Include lighting** - dramatically affects mood
7. **Iterate** - refine based on results
8. **Use consistent seeds** for variations (when possible)

---

## Limitations

- Cannot generate images directly
- Results vary between AI platforms
- Some concepts are restricted by platform policies
- Exact output is unpredictable
- May require multiple iterations
