Can sharpening fix a very blurry photo?

Sharpening can improve slightly soft or out-of-focus images significantly, but cannot recover information from severely blurred photos.

What is the threshold parameter?

Threshold controls the minimum tonal difference required before sharpening is applied. Higher values prevent sharpening flat areas like skies, reducing noise amplification.
