I noticed recently a few links for Linux users (but not only, read on) who wish to reduce blur on their photos:

  • Unshake is a free photo editing software written in Java that can remove blurs from your photos. It can be used on virtually any platform (Linux, PC, Mac, etc.)
  • GIMP is the GNU/Linux-based photo editing software. It also exists in versions for Windows, Mac OS X. Since it has a full system of plug-ins, you can go quite far (including improving your photos with the Refocus-It and Iterative Refocus plug-ins for sharpening the photos).
  • Another specific noise-reduction plug-in for GIMP is the GREYCstoration plugin (it will work well to improve photographs shot at high ISO levels).

That’s worth trying, isn’t it?

Besides, an for those of you who are strictly interested in using GIMP, there are additional resources to check:

Now, I would like to underline the quality of a full series of posts, published by Patrick Moll on Alpha Numérique, and dedicated to comparing as precisely as possible the various offers now on the market to develop and improve as much as possible the pictures that -sometimes- we must shoot using very high levels of ISO sensitivity (with the troubling levels of digital noise that come with big ISO levels).

The list of the software programs taken into account is quite respectable:

  • Image Data Converter 3
  • Lightroom 3 / Camera Raw 6
  • DxO Optics Pro 6
  • Aperture 3
  • Bibble Pro 5
  • Capture One Pro 5
  • ACDSee Pro 3
  • Silkypix 4
  • Lightzone 3
  • Raw Developer 1 (dcraw)

Not bad, eh!

Even if the comparisons done here are not only for Sony photo cameras, Patrick Moll applied its tests to a quite appreciable list of cameras too:

Even if you are not reading French, I highly recommend checking these (most of the posts are made of image comparisons using the yellow buttons to select the software program results you want to see). Even if you are equipped with Pentax, Canon or Nikon gear, the lessons you will draw from this are applicable on all the photo camera brands, concerning strengths and weaknesses of each of these software tools.

To understand the review process and the methodology, I would recommend the reading of (here, all in French):

With the tests, body by body, you will immediately recognize the excellent results of Lightroom 3/Camera Raw 6 (these two Adobe software programs share a single common RAW file management core). Just behind, comes DxO Optics Pro 6 which is a bit more violent (or more accentuation prone) and the (not famous enough) Bibble Pro 5.

From this point, you will always be able to get the best from the photos you were forced into shooting in poor lighting conditions which required big ISO figures.
