Frequently asked questions
Can sharpening fix an out-of-focus photo?
It improves edge contrast but cannot recover detail that was never captured. Sharpening works best on photos that are only slightly soft.
Can I over-sharpen a photo?
Yes, too much strength adds halos around edges and makes grain look harsh. Preview and back off until the edges look clean.
Should I sharpen before or after resizing?
Sharpen after resizing. Resizing blurs edges slightly, so a final sharpen gives the crispest result for the exact output size. Use resize JPG first, then sharpen.
