-    ### 📼 VHS Video Still Features:
-    
-    **🎥 Camcorder UI Elements:**
-    - Authentic REC indicator with red dot
-    - MENU, ZOOM, and control button overlays
-    - LIGHT, TITLER, PLAY indicators
-    - Multiple UI styles (Classic, Sony, Panasonic)
-    
-    **📺 VHS Video Artifacts:**
-    - **Resolution Loss**: Simulates VHS 240-line horizontal resolution
-    - **Color Bleeding**: Horizontal chroma smearing typical of VHS
-    - **Tracking Lines**: Random horizontal line displacement
-    - **Interlacing**: Field offset and line-by-line artifacts
-    - **Tape Wear**: Dropouts, streaks, and degradation
-    - **Head Switching Noise**: Noise band at bottom of frame
-    - **RF Interference**: Wavy interference patterns
-    
-    **⏰ Timestamp Options:**
-    - **Camcorder**: Bottom-left PM time format (like Image 2, 8, 9)
-    - **Security**: Top-right format with full date (like Image 7)
-    - **European**: Bottom-right DD.MM.YYYY format (like Image 3, 5)
-    
-    **🎯 Perfect for Creating:**
-    - Russian 2000s family video stills
-    - Security camera footage aesthetics
-    - Amateur camcorder recordings
-    - VHS home movie screenshots
-    - Y2K-era video content
-    
-    **💡 Pro Tips:**
-    - Enable VHS mode for full video aesthetic
-    - Use "Classic" UI style for most authentic look
-    - Combine with higher compression for maximum authenticity
-    - "Camcorder" timestamp matches Russian family videos
-    - Reduce resolution loss for cleaner look, increase for more authentic VHS degradation
-    
-    **🔧 Technical Features:**
-    - Simulates actual VHS color space limitations
-    - Authentic interlacing and field offset
-    - Real tracking error patterns
-    - Period-accurate UI design based on 90s/2000s camcorders
-    - Proper aspect ratio handling for video frames
+    ### 🎯 ENHANCED: Reference Style Transfer Features:
+    - **Upload Reference Photos**: 1-5 authentic Russian 2000s photos for style matching
+    - **Color Matching**: Matches lighting, color grading, and atmosphere
+    - **Texture Matching**: Adjusts contrast and visual texture based on references
+    - **Enhanced Amateur Mode**: Full point-and-click camera emulation with:
+      - **Center-weighted metering** simulation (subjects properly exposed, backgrounds over/under)
+      - **Flash characteristics** (harsh falloff, foreground overexposure, cool color cast)
+      - **Depth-based focus** (amateur focus patterns, background blur)
+      - **Limited dynamic range** (shadow crushing, highlight clipping)
+      - **Exposure patterns** typical of 2000s compact cameras
+    
+    ### 💡 Enhanced Style Transfer Tips:
+    - **Best references**: Family photos with flash, indoor gatherings, amateur compositions
+    - **Enhanced Amateur mode**: Gives most authentic point-and-click camera results
+    - **Flash photos work best**: References with visible flash create realistic amateur lighting
+    - **Center-composed photos**: Works best with typically amateur-style center composition
+    
+    ### 📸 What Enhanced Mode Emulates:
+    - **Point-and-click cameras**: Canon PowerShot, Nikon Coolpix, Sony Mavica
+    - **Center-weighted metering**: Subjects in center properly exposed, backgrounds blown/dark
+    - **On-camera flash**: Harsh, direct flash with realistic falloff and color temperature
+    - **Amateur focus patterns**: Everything in focus OR poorly focused backgrounds
+    - **Cheap optics**: Limited dynamic range, highlight clipping, shadow crushing
+    
+    ### 🎬 Recommended Workflow:
+    1. Upload your modern photo
+    2. Upload 3-5 flash photos from Russian family gatherings (1998-2002)
+    3. Enable "Enhanced Amateur" style transfer (strength 0.6-0.7)
+    4. Choose "Kitchen Party" or "Apartment Interior" scene preset  
+    5. Use tungsten white balance + compression 0.9 for authentic look
+    6. Process and get genuine point-and-click camera results!
+    
+    ### 🔧 Updated Default Settings:
+    - **Block Size**: Now 8px (was 16px) for finer, more realistic artifacts
+    - **White Balance**: Tungsten default (most common Russian indoor lighting)
+    - **Compression**: 0.9 default (typical of 2000s digital cameras)
+    - **4:3 Crop**: Now default ON (authentic camera aspect ratio)
+    - **Intensity**: 3.5 default (slightly more effect for amateur camera look)
