Download Unshake

Editor: Unshake 1.5 is a Java-2 and C 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. Because it is written in Java, once you have installed Sun's Java 2 all you have to do is to unzip one file to install Unshake on your computer. (The Java Runtime Environment is about 8 MBytes, but growing - if you are prepared to work in the English of the USA and use earlier code, the USA version 1.3 of the JRE is only about 5 MB.) A test version for Macs is available.

Also included in this distribution is a library and command-line filter for Linux, UnshakeC1.5r1.

Unshake is offered free for personal use.

This is an example of what it can do; Below is a small part of a picture I took with a cheap Polaroid camera, blown up to 600 dpi. It was a sunny late afternoon in May, so the contrast Between sunlit leaves and shadow was quite dazzling. (Click on the picture to see the full image.)
