Tips for best results
- Mild sharpening (intensity 1-2) is best for photos that are only slightly soft — rescues focus without making the image look harsh.
- Strong sharpening (intensity 4+) is for text, scanned documents, or screenshots where you want crisp edges.
- Over-sharpening introduces noise and halos around edges — if the photo looks gritty, dial it back.
- Sharpening cannot recover detail that wasn’t captured — truly blurry images won’t become magically clear, but slight focus issues can be dramatically improved.
- For best print results, sharpen as the LAST step in your editing workflow — after resizing, color correction, and watermarking.
