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
