A handy tool for improving the quality of digital photos. Unshake is an automatic deconvolver, also known as a "blind" deconvolver. Most image processors offer pre-defined filters which have been found useful after a lot of use. They bring out hidden detail by emphasising changes (like edges) in pictures.

Distinct from this, deconvolvers try to recover what the original scene looked like, but they have the problem that one needs to specify exactly how the picture was blurred in the first place (for example, if the camera was poorly focused, one would ideally specify not just how bad the focus was, but how fast the shutter moved at each phase of its cycle, and how many leaves the shutter had).

An automatic deconvolver attempts to estimate itself how the picture was blurred in the first place, then to deduce what the original scene would have looked like. This is a very difficult task, involving automatically setting dozens or hundreds of controls.

Unshake can only usually double or treble the resolution of a blurred picture. Nonetheless, Unshake is still, after first being released in August 2000, the only automatic deconvolver available which works on normal domestic photographs, the only free automatic deconvolver designed for non-specialists to use, and the only.

Unshake can also remove dithering and rasters, and it can work through the lines found on magazine pictures, though for copyright reasons I can't put examples of Unshaken magazine pictures on the website.

But the real point of Unshake is that it does it automatically. You can be certain that there are filters which produce the same results as I have given here (because Unshake found one such filter), and there are some which will give results which look sharper. But Unshake is designed to seek the lingering real information which has been obscured in the image.

To Launch Unshake under Windows
1.If you want to avoid browsing for them later, put the images (PNG, GIF or JPEG files) you want to Unshake in the folder called "source" in the Unshake folder.
2.Double-click on the file in the Unshake folder called "Launch". This assumes that Sun's Java 2 is already installed in one of several standard locations.
