-### ✅ What We Built
+### ✅ What We Built - ENHANCED VERSION
 
 A complete **AI-powered agricultural photo keyword tagging system** that:
 
-1. **Automatically generates 5-10 relevant keywords** for agricultural stock photos
+1. **Automatically generates 5-10 relevant keywords** with agricultural distinctions (farmer vs rancher)
 2. **Creates descriptive titles** suitable for stock photo platforms
-3. **Processes images in batches** (tested with 7 images, scalable to 500+)
+3. **Processes images in batches** with quality validation and performance tracking
-4. **Outputs results in CSV format** exactly as specified
+4. **Outputs results in CSV format** exactly as specified + quality scores
-5. **Uses state-of-the-art BLIP-2 model** for image understanding
+5. **Uses state-of-the-art BLIP-2 model** with enhanced agricultural recognition
+6. **Advanced location extraction** from GPS EXIF data
+7. **Quality validation system** with scoring and issue detection
+8. **Batch processing utilities** for handling 500+ images efficiently
