# 🎨 Unified UGC Platform - Photogen1

A unified ComfyUI-powered platform for ultra-realistic UGC photo generation with face enhancement capabilities.

## 🚀 Features

- **Authentic UGC Style**: Generate photos that look like real smartphone photography
- **Face Enhancement**: Improve facial details using GFPGAN
- **Multiple Workflows**: Portrait, Full Body, Street Photography, and FLUX styles
- **Authenticity Stack**: Carefully curated models and LoRAs for maximum realism
- **Real-time Generation**: GPU-accelerated ComfyUI backend

## 🎯 The Authenticity Stack

This platform uses a carefully selected stack of models designed to produce images that look like genuine user-generated content:

### Base Models
- **RealVisXL V4.0**: Foundation checkpoint for exceptional photorealism
- **SDXL VAE**: Standard VAE for accurate color and light rendering

### LoRA Stack (Applied in sequence)
1. **epiCRealism - Natural photographic** (0.6): Creates the "phone camera" aesthetic
2. **Detail Tweaker XL v2** (0.4): Adds realistic skin texture and fabric details
3. **Film Grain Helper SDXL** (0.3): Introduces authentic camera sensor noise

### Face Enhancement
- **GFPGANv1.4**: For face restoration and enhancement

## 🛠️ Setup

The application automatically:
1. Downloads all required models on first run
2. Clones ComfyUI and necessary custom nodes
3. Sets up the complete environment

No manual setup required!

## 🎨 Optimal Settings for UGC

Pre-configured for authentic results:
- **Sampler**: DPM++ 2M SDE Karras (adds organic randomness)
- **CFG Scale**: 5.0 (lower values = more natural, less "AI" look)
- **Steps**: 25-30 (sufficient for quality without overprocessing)

## 💡 Usage Tips

### For Best UGC Results
- Use prompts that describe real scenarios: "selfie in bedroom, iPhone photo, natural light"
- Include imperfections: "slightly messy background", "casual outfit"
- Avoid professional terms: Skip words like "professional", "studio", "perfect"

### Example Prompts
**Good**: "woman taking mirror selfie in bathroom, smartphone photo, morning light, no makeup, oversized t-shirt"

**Avoid**: "professional portrait of beautiful model, studio lighting, high quality"

## 🚀 Performance

- T4 GPU: ~30-45 seconds per image
- A10G GPU: ~15-20 seconds per image
- Face enhancement: +10-15 seconds

## 🐛 Troubleshooting

- **Model download fails**: Check internet connection, HF Space will retry
- **OOM errors**: Reduce image dimensions or batch size
- **Slow generation**: Normal on free tier, upgrade to faster GPU
