SmartDeblur is a clever graphics tool which uses advanced mathematical techniques to help sharpen blurry digital photos.

Don't be put off by the science, though - the program is even easier to use in this new version. Drag a slider, click "Analyze Blur" and watch as SmartDeblur automatically figures out the blur type, and applies its corrections.

You will need to be patient, because SmartDeblur can take a while to work. But the example image proves it can be worth the wait, showing absolutely spectacular improvements.

Other images didn't fare as well, but you can tune the results considerably by selecting a different "Analyze Blur" area.

Smart Deblur 2.3: "2x faster, command-line interface, RAW supports, 45 Mpx images".
