Blur has three causes and one fix
Missed focus, camera shake and heavy compression all destroy edges. The model rebuilds those edges rather than sharpening what is left.
What it can and cannot recover
Mild to moderate blur comes back convincingly. Severe motion blur is reconstruction, not recovery, so treat the result as a new image.
Also known as a photo sharpener
Same job, different words. If the photo is old or noisy rather than blurry, the photo enhancer handles that case.
FAQ
Does it work on faces?
Yes. Face restoration runs inside the same pass, which is where most of the perceived sharpness comes from.
Will it invent detail?
On heavy blur, yes. Keep the original file if the image has to serve as evidence.
What does it cost?
A flat rate per image, shown before you run it. Failed runs release their credits.
Is this a photo sharpener?
Yes. Photo sharpener, image deblur and unblur all land here. One pass rebuilds the edges.
