Getting Started: Complete Setup Guide
Step 1: Install Stable Diffusion
Using WebUI (Recommended for beginners):
git clone https://github.com/AUTOMATIC1111/stable-diffusion-webui.git cd stable-diffusion-webui ./webui.sh # or ./webui.bat on Windows
Takes 5-10 minutes. Automatically downloads model and dependencies.

Prompt Engineering: The Art & Science
Before & After Examples
Bad Prompt:
"a girl with a camera"
Results: Blurry, inconsistent, amateur quality
Good Prompt:
"professional portrait of a 25-year-old woman, holding Canon R5 camera, studio lighting, soft shadows, 50mm lens, sharp focus on face, flawless skin, natural makeup, wearing fashionable outfit, trending on artstation, 8k resolution, highly detailed"
Results: Sharp, professional, consistent quality across generations
Prompt Formula Template
[Subject] + [Pose/Action] + [Setting] + [Technical Details] + [Quality Tags]
Example breakdown:
- Subject: "professional Instagram influencer, woman"
- Pose: "standing confidently, looking at camera"
- Setting: "minimalist studio with soft golden light"
- Technical: "sharp focus, 85mm portrait lens, f/1.8"
- Quality: "trending on Instagram, professional photography, 8k"
Common Mistake: Token Weight Overload
Wrong: "(beautiful:1.5) (gorgeous:1.4) (stunning:1.6)"
Causes conflicting generation. Use sparingly - only for critical elements like "(face:1.2)" or "(hands:1.3)"
Use Case Applications for Content Creators
Fashion Content Calendar Planning
Generate outfit variations in advance to plan monthly content. Create consistent posting schedule without daily photoshoots. Test different styles before investing in real clothing.
Benefit: Maintain consistent posting schedule regardless of travel or availability
Virtual Character Development
Create fully synthetic characters for brand building. Maintain consistent appearance across hundreds of posts using same seeds and LoRAs. Build persona without location or appearance constraints.
Benefit: Complete control over brand aesthetics and character consistency
Product Lifestyle Photography
Generate lifestyle context for products (fashion, accessories, digital products). Create multiple scene variations quickly. Test different presentation styles.
Benefit: Rapid iteration on visual concepts before final production
Content Inspiration & Mood Boards
Generate reference images for real photoshoots. Create mood boards for brand aesthetics. Visualize concepts before executing with photographer.
Benefit: Clear visual communication with creative teams and photographers
Advanced Techniques for Consistency
Character Consistency: Fixed Seed + LoRA Method
To create a consistent virtual influencer across hundreds of images:
Step-by-Step Process:
- 1. Generate initial reference image with detailed prompt describing face, hair, body type
- 2. Record seed number that produces desired look (e.g., seed: 12345678)
- 3. Train custom LoRA on 15-20 images of this character (using DreamBooth or Textual Inversion)
- 4. For all future generations: Use same seed + load your custom LoRA
- 5. Only vary: Outfit, pose, background in prompt
Result: 95%+ facial consistency across all images
Negative Prompt Engineering
Critical negative prompts for professional influencer images:
Recommended negative prompt template:
low quality, blurry, out of focus, jpeg artifacts, watermark, text, logo, bad anatomy, deformed hands, extra fingers, missing fingers, fused fingers, bad proportions, asymmetric face, crossed eyes, lazy eye, malformed limbs, poorly drawn face, cloned face, gross proportions, mutated, disfigured
Pro Tip: Save this as a preset to apply to every generation
Weighted Token Strategy
Control prompt emphasis using parentheses and weights:
Syntax:
(keyword:weight) where 1.0 is default
Lower weight (0.5-0.9) = less emphasis
Higher weight (1.1-1.5) = more emphasis
Example:
"professional portrait, (beautiful face:1.3), (sharp eyes:1.2), casual outfit, (blurred background:0.8)"
This emphasizes face quality while de-emphasizing background detail
Warning:
Avoid weights above 1.5 - causes distortion. Use sparingly (2-3 weighted terms max per prompt).
Legal & Ethical Considerations
Disclosure Requirements
FTC guidelines require disclosure of AI-generated content used for commercial purposes:
- • Clearly disclose if images are AI-generated (in bio or post caption)
- • Use hashtags: #AIGenerated #VirtualInfluencer #AIPhotography
- • For sponsored content: Disclose both AI nature AND sponsorship
- • Many platforms (Instagram, TikTok) are developing AI content labels
Copyright & Ownership
Understanding rights to AI-generated images:
- • YOU own images generated on your local machine (Stable Diffusion)
- • Cloud services (Midjourney, DALL-E) have specific terms - read carefully
- • Cannot use AI to recreate copyrighted characters or trademarked logos
- • Training data copyright is evolving - use ethically sourced models
- • Commercial use typically allowed for self-generated content
Ethical Best Practices
- • Don't create deepfakes of real people without consent
- • Avoid generating realistic images that could mislead (fake news, false events)
- • Consider diversity and representation in virtual characters
- • Be transparent about AI use, especially with brand partnerships
- • Respect platform guidelines on synthetic media disclosure

CFG Scale (Prompt Adherence)
- 7-8: Flexible, creative results
- 9-12: Balanced (recommended)
- 13-15: Strict prompt following
- 16+: Oversaturated, artifacts
Steps (Quality vs Speed)
- 20: Fast, decent quality
- 30-40: Best quality/speed ratio
- 50+: Diminishing returns
Sampler Comparison
- Euler: Fast, good quality
- DPM++: Sharp details, pro choice
- DDIM: Slower but stable
Seed (Reproducibility)
- -1: Random (new variation)
- Fixed number: Exact reproduction
Pro Tip: Optimal Influencer Setup
CFG: 11 | Steps: 35 | Sampler: DPM++ 2M | Resolution: 768x768
Generates professional portrait in 45-60 seconds with highest quality/speed ratio
Complete Workflow Examples with JSON
Workflow 1: Instagram Portrait Pipeline
Step-by-step nodes:
- 1. Load Deliberate model
- 2. Generate base image (768x768)
- 3. Apply upscaling (2x)
- 4. Use detailer nodes for face enhancement
- 5. Export at 2000x2000 for Instagram feed
Output: 4 variations ready to post
Workflow 2: Batch Outfit Generation
For content creators needing multiple outfits:
- 1. Load same character/person seed
- 2. Generate 10 images with different outfit prompts
- 3. Batch upscale all results
- 4. Auto-organize into folders by outfit type
Time saved: 2 hours vs traditional photoshoot

Troubleshooting Common Issues
Problem: "CUDA out of memory" errors
Solution: Reduce resolution from 768 to 512, lower batch size to 1, or use CPU mode
Problem: Blurry or low-quality faces
Solution: Add "highly detailed face, sharp focus on eyes" to prompt. Use Face Detailer node. Increase CFG to 12
Problem: Inconsistent character appearance
Solution: Fix seed number. Use LoRA with character training. Add specific details in each prompt (eye color, hair style)
Problem: Bad hands/anatomy
Solution: Add "hands visible:0" to negative prompt. Crop out hands. Use detailer for extremities
