Are you looking for some examples about how to use Blurity?

If so, the Features page might be useful, since it shows real images being deblurred.

You can download those same blurry images from the links to the right and try to reproduce the results yourself. If you get stuck, you can refer to the screenshots that are included in the examples.

The Blurity user manual includes descriptions of the various parameters. It provides hints about how to make Blurity perform successfully for you.

Want some blurry images to experiment with?

Give these a try:


Several questions frequently come up in support emails. Generally, they stem from over-optimism with respect to Blurity's capabilities. (Sadly, Blurity cannot always work miracles.) So, a few things to note:

  • Blurity DOES NOT work on severely out-of-focus images
  • Blurity DOES NOT enlarge small images, nor does it "deblur" enlarged images
  • There almost certainly will be some visual artifacts after deblurring unless the blur is relatively small

For more information about Blurity's capabilities and limitations, plus directions about how to use Blurity's various settings to maximize your chances of successful deblurring, please see the Blurity user manual.

Known issues and recent changes

Open issues:

  • Installing Blurity as an administrator on Windows Vista, Windows 7, or Windows 8 will prevent non-admin users from also installing Blurity
  • If user's directory on Windows is at a UNC path, image processing will fail
  • Certain tools that aggressively delete temporary files will cause image processing to fail
  • Deblurring will be substantially slower on computers with AMD processors versus those with Intel processors
