Understanding Sharpness

  • Edge contrast: How distinct edges are (Laplacian variance)
  • Gradient strength: Overall edge magnitude (Sobel operator)
  • Causes of softness: Missed focus, camera shake, diffraction, lens quality
  • Note: Intentionally soft images (portraits, artistic blur) will score lower
  • Heatmap: Green = sharp areas, Red = soft areas
