Download Unshake, to sharpen blurred and shaken pictures
Unshake is a free (for personal use) program which improves blurred and shaken photographs by working out the form of the blurring, then deducing what the picture would have looked like if it had not been blurred. Unshake is written in Java (you need to have installed Sun’s Java).
Unshake can also remove dithering and rasters, and it can work through the lines found on magazine pictures. The real point of Unshake is that it does everything automatically. You can be certain that there are filters which produce the same results, 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.
