When to Sharpen

Scenario	Sharpening Level	Notes
Slightly soft photo	Low (10-30%)	Preserves natural look
Scanned documents	Medium (30-60%)	Improves text readability
Resized/downscaled image	Medium (30-50%)	Restores lost detail
Motion blur recovery	High (60-100%)	Cannot fully fix heavy motion blur

Practical Tips

• Don't over-sharpen — excessive sharpening creates visible halos around edges and amplifies noise.
• Sharpen as the last step after resizing or color correction for best results.
• Use a higher threshold to sharpen edges without amplifying grain in smooth areas like skies.

Can sharpening fix a completely blurry photo?

Sharpening enhances existing edge detail but cannot recover information lost to severe motion blur or focus issues. It works best on slightly soft images.

Does sharpening increase file size?

Slightly, yes. Sharper edges contain more high-frequency data, which compresses less efficiently in JPG format.
