Essential Preparation

📱 Device Setup

  • Clean Camera Lens: Remove fingerprints and dust for crystal-clear images
  • Stable Hands: Use both hands or a tripod for steady shots
  • Full Battery: Ensure sufficient power for extended scanning sessions
  • Storage Space: Clear memory for high-resolution document captures
  • App Selection: Use professional scanning apps like DocuMaster

📄 Document Preparation

  • Flatten Documents: Remove creases and folds for better edge detection
  • Clean Surface: Ensure documents are free from dirt and marks
  • Separate Pages: Scan multi-page documents individually for best results
  • Remove Staples: Eliminate shadows and scanning obstructions
  • Check Orientation: Ensure text is readable and properly aligned

Optimal Lighting Techniques

💡

Natural Light Sources

Natural light provides the most balanced illumination for document scanning:

✅ Best Practices

  • • Scan near large windows
  • • Use diffused daylight
  • • Avoid direct sunlight
  • • Position document perpendicular to light

❌ Avoid

  • • Harsh direct sunlight
  • • Backlit conditions
  • • Mixed light sources
  • • Strong shadows
🔦

Artificial Lighting Setup

When natural light isn't available, create optimal artificial lighting:

Two-Point Lighting

Position two light sources at 45-degree angles on either side of the document to eliminate shadows and ensure even illumination.

Overhead Lighting

Use bright, diffused overhead lighting for consistent results. LED panels work best for color accuracy.

Perfect Camera Angles & Positioning

📐 Optimal Positioning

Distance & Height

  • Distance: 12-18 inches from document
  • Height: Camera directly above center
  • Parallel: Keep phone parallel to document
  • Stability: Use both hands or tripod

Angle Guidelines

  • Perpendicular: 90-degree angle to surface
  • No Tilt: Avoid keystoning effects
  • Full Coverage: Include entire document
  • Margins: Leave small border around edges

Advanced Capture Techniques

📸 Camera Settings

  • Focus Mode: Use auto-focus or manual focus
  • Exposure: Tap to focus and set exposure
  • Flash: Generally avoid, use natural light
  • HDR: Enable for challenging lighting
  • Resolution: Use highest available setting
  • Grid Lines: Enable for better alignment

🎨 Color & Contrast

  • White Balance: Adjust for accurate colors
  • Contrast: Ensure text stands out clearly
  • Saturation: Keep colors natural
  • Brightness: Avoid overexposure
  • Shadows: Minimize dark areas
  • Highlights: Prevent blown-out whites
