Blurred photos are caused by the lack of auto-focus feature, when people forget to turn it on, or the far more common reason if the camera is shaken when photos are taken. If the image is important to you and there’s no chance of taking the shot once again, then fixing that blur is your only option. Here’s how you can do that with SmartDeblur.

How to Fix Blurred Images and Out Focus Images with SmartDeblur:

Click the Open button in the top left corner and select the images which are blurred or if you want, select the test image offered by SmartDeblur at the welcome window. In either case you should see something like this:

SmartDeblur before conversion

First select the Defect type, from the three previously mentioned, and then use the settings in the top right corner like Blur Parameters and Kernel Preview & Tuning, to correct the focus. Start with the Radius. Slide it to the right and look at the image. At some point, depending on how blurry the image is, you should see an improvement. Moving the slider more than its needed will cause the blur to come back. Switch to Smooth and then in the right settings window use Correction Strength slider for fine tuning.

SmartDeblur after blur correction

Completely blurred text from the image before is now readable, to some extent, it’s definitely much better than it was before. Even more precise blur correction can probably be made, you just need to play around with settings more to find the right spot where the focus restoration is the best, click Save, and you’re done.


Even though SmartDeblur isn’t restoring out of focus images completely, it does make them viewable, see before and after images above. If your favorite photos turned out to be blurry, this is definitely the tool to try, it’s free so it costs you nothing to try it out. Try SmartDeblur for free.
