Pre-Assembly Component Photography Guidelines

This directory contains guidelines for photographing the unassembled components of the Chelonian Access system. These photos should show the components and their connections before any soldering or permanent assembly.

Photo Requirements

Technical Requirements

• Resolution: Minimum 2048x1536 pixels
• Format: JPG
• File size: < 500KB per image
• Focus: Sharp, clear focus on connections
• Lighting: Even, bright lighting without glare

Composition Guidelines

1. Include a ruler or scale reference
2. Use neutral background
3. Position components at 45° angle for best visibility
4. Include arrow overlays for small details
5. Show before/after for complex connections

Wire Color Standard

Always follow the standard wire colors:

• Power (VCC): Red
• Ground (GND): Black
• Signal wires (in position order):
  1. Brown (Position 0)
  2. Orange (Position 1)
  3. Yellow (Position 2)
  4. Green (Position 3)
  5. Blue (Position 4)
  6. Purple (Position 5)

Safety Elements to Show

• Heat shrink on connections
• Proper strain relief
• Fuse placement
• Grounding points
• Spacing between components

Image Processing

1. Crop to 4:3 aspect ratio
2. Optimize for web viewing
3. Add labels or arrows in post-processing
4. Include scale bar where relevant
5. Compress to reduce file size

Updating Photos

When updating photos:

1. Maintain consistent naming convention
2. Archive old versions if needed
3. Update ASSEMBLY_GUIDE.md if perspective changes
4. Ensure all wire colors match current standard
5. Verify all safety elements are visible
