--- name: image-prompt-engineer description: "Expert photography prompt engineering skill for AI image generation. Use when: generating prompts for Midjourney/DALL-E/Stable Diffusion/Flux, creating product shots, portraits, landscapes, fashion photography, or any visual content that needs precise AI-generated imagery. Triggers on: 'write a prompt', 'AI image', 'Midjourney prompt', 'DALL-E prompt', 'generate an image of', 'product photography prompt'." --- # Image Prompt Engineer 📷 Expert at crafting detailed, structured prompts for AI image generation tools (Midjourney, DALL-E, Stable Diffusion, Flux). ## Core Workflow 1. **Concept Intake** — Understand visual goal, platform, style, brand requirements 2. **Reference Analysis** — Lighting, composition, style elements from references 3. **Prompt Construction** — Layer: Subject → Environment → Lighting → Technical → Style 4. **Optimization** — Negative prompts, platform-specific syntax, quality enhancers 5. **Documentation** — Save successful patterns ## Prompt Structure Framework ### Layer 1: Subject ``` - Primary subject (person, object, scene) - Details: age, ethnicity, expression, attire, textures, materials - Interaction with environment - Scale and proportion ``` ### Layer 2: Environment ``` - Location type (studio, outdoor, urban, natural, interior) - Environmental details (weather, time of day, textures) - Background treatment (sharp, blurred, gradient, minimalist) - Atmospheric conditions (fog, rain, haze, clarity) ``` ### Layer 3: Lighting ``` - Light source (golden hour, overcast, softbox, neon, rim light) - Light direction (front, side, back, Rembrandt, butterfly, split) - Light quality (hard/soft, diffused, specular, volumetric) - Color temperature (warm, cool, neutral, mixed) ``` ### Layer 4: Technical (Photography Specs) ``` - Camera perspective (eye-level, low angle, bird's eye, worm's eye) - Focal length effect (wide angle, telephoto compression, standard) - Depth of field (shallow for portrait, deep for landscape) - Exposure style (high key, low key, balanced, HDR, silhouette) ``` ### Layer 5: Style ``` - Photography genre (portrait, fashion, editorial, commercial, documentary, fine art) - Era/period (vintage, contemporary, retro, futuristic, timeless) - Post-processing (film emulation, color grading, contrast, grain) - Reference photographers (Annie Leibovitz, Peter Lindbergh, etc.) ``` ## Genre Templates ### Portrait ``` [Subject: age, ethnicity, expression, attire] | [Pose and body language] | [Background treatment] | [Lighting: key, fill, rim, hair light] | [Camera: 85mm, f/1.4, eye-level] | [Style: editorial/fashion/corporate/artistic] | [Color palette and mood] | [Reference photographer] ``` ### Product Photography ``` [Product description with materials and details] | [Surface/backdrop description] | [Lighting: softbox positions, reflectors, gradients] | [Camera: macro/standard, angle, distance] | [Hero shot/lifestyle/detail/scale context] | [Brand aesthetic alignment] | [Post-processing: clean/moody/vibrant] ``` ### Landscape ``` [Location and geological features] | [Time of day and atmospheric conditions] | [Weather and sky treatment] | [Foreground, midground, background] | [Camera: wide angle, deep focus, panoramic] | [Light quality and direction] | [Color palette: natural/enhanced/dramatic] | [Style: documentary/fine art/ethereal] ``` ### Fashion ``` [Model description and expression] | [Wardrobe details and styling] | [Hair and makeup direction] | [Location/set design] | [Pose: editorial/commercial/avant-garde] | [Lighting: dramatic/soft/mixed] | [Camera movement: static/dynamic] | [Magazine/campaign aesthetic reference] ``` ## Platform Syntax ### Midjourney ``` /imagine prompt: [subject] --ar 16:9 --v 6 --style raw --chaos 5 --seed [n] --ar → aspect ratio --v → version (5, 6, etc.) --style → style mode --chaos → variation (0-100) --seed → reproducibility --no → negative prompt :: → weighted emphasis ``` ### DALL-E ``` Natural language, conversational Style mixing: "in the style of [X] mixed with [Y]" Be specific about what you want ``` ### Stable Diffusion ``` [subject], [details], [lighting], [style] Negative: [unwanted elements] (lora:model:weight) → LoRA weighting [[REDACTED_SECRET] → explicit weighting ``` ### Flux ``` Detailed natural language descriptions Photorealistic emphasis Less need for photography jargon ``` ## Negative Prompts (Midjourney/SD) ``` --no blurry, low quality, distorted, watermark, text, logo, noisy (negative weighting where supported) ``` ## Photography Terminology (Use Correctly) | ❌ Vague | ✅ Technical | |---------|-------------| | Blurry background | Shallow depth of field, f/1.8 bokeh | | Big picture | Wide-angle, 24mm, environmental portrait | | Dark shadows | Deep shadows, high contrast, Rembrandt lighting | | Nice lighting | Soft golden hour, butterfly lighting, rim light | | Old looking | Film grain, Kodak Portra 400, faded contrast | ## Success Metrics - Generated images match concept ≥ 90% first attempt - Consistent results across generations - Technical elements (lighting, DOF, composition) render accurately - Minimal iteration needed - Suitable for professional/commercial use ## Reference Files -

path: references/platform-syntax.md
content: # Platform Syntax Reference

## Midjourney

### Basic Syntax
```
/imagine prompt: [full description]
```

### Parameters
| Flag | Meaning | Example |
|------|---------|---------|
| `--ar` | Aspect ratio | `--ar 16:9`, `--ar 1:1` |
| `--v` | Version | `--v 6`, `--v 5.2` |
| `--style` | Style mode | `--style raw` |
| `--chaos` | Variation (0-100) | `--chaos 50` |
| `--seed` | Reproducibility | `--seed 12345` |
| `--s` | Stylize | `--s 250` |
| `--no` | Negative | `--no text, watermark` |
| `--iw` | Image weight | `--iw 0.5` |
| `--tile` | Tileable | `--tile` |
| `--cref` | Character reference | `--cref [url]` |
| `--sref` | Style reference | `--sref [url]` |

### Weighted Emphasis
```
 Subject ::weight   → higher weight = more emphasis
 (Subject)          → grouping
 Subject::0.5       → lower weight
```

### Useful Shortcuts
```
--q  → quality (1 or 2)
--w  → weirdness
--e  → explore (variation)
--re  → remix mode
```

## DALL-E

### Natural Language Optimization
- Write conversationally but precisely
- Specify exact colors, materials, textures
- Mention style混合: "in the style of X mixed with Y"
- Be explicit about composition

### Examples
```
"A professional product photograph of a minimalist watch on a marble 
surface, soft side lighting from the left, shallow depth of field 
with the watch in sharp focus and the background softly blurred, 
clean white backdrop fading to light gray, commercial photography 
style reminiscent of Apple product shots"

"An elderly man sitting on a wooden bench in a park, warm autumn 
light filtering through golden leaves, candid documentary style, 
slight motion blur on the leaves, Kodak Portra 400 film look, 
shallow depth of field, gentle smile, weathered hands"
```

## Stable Diffusion

### Prompt Syntax
```
[positive prompt], [more details], [lighting], [style]
Negative prompt: [unwanted elements]
```

### Weighting
```
(cat)              → weight 1.1
((cat))            → weight 1.21
(cat:1.5)         → explicit weight 1.5
[cat]             → weight 0.9
```

### LoRA
```
<lora:model_name:weight>  → LoRA model引用
<lora:lora_name:0.5>      → 50% strength
```

### Embeddings
```
bidish:0.7             → embedding reference
easynegative           → common negative embedding
```

### ControlNet
```
--controlnet model     → depth, canny, pose, etc.
--controlnet weight    → 0-2 range
--controlnet guidance  → guidance strength
```

## Flux

### Best Practices
- Detailed natural language descriptions
- Photorealistic is default strength
- Less jargon needed than Midjourney
- Still specify: subject, lighting, style, mood
- Use "photorealistic" explicitly if that's the goal

### Example
```
"A close-up portrait of a young woman with freckles and green eyes, 
natural makeup highlighting her features, soft window light from the 
right creating gentle shadows, shallow depth of field, skin texture 
visible and detailed, magazine editorial quality, neutral gray background, 
commercial beauty photography style, 85mm f/1.4"
```

## Common Parameters Across Platforms

| Feature | Midjourney | Stable Diffusion | DALL-E | Flux |
|---------|-----------|-----------------|--------|------|
| Aspect ratio | `--ar` | `--W --H` or aspect ratio | Auto | Auto |
