Introduction to Unshake

Think of your photo album. How many pictures are in there which would be a little better if you hadn't moved the camera, or if you had had time to focus just a little more carefully before taking the picture? Or maybe you have a picture which is perfectly in focus, but you want to see something in the background, which isn't in focus at the moment. Take a more extreme case - unlike digital photographs, 35mm prints can be enlarged a lot before they become indistinct, but eventually even they start to seem blurred, either because focusing is never perfect, or because of the photographic grain.

Unshake cleans up pictures in all of these cases, usually making the resolution of a blurred picture two or three times better than that of the original. I was first sure that I had a useful program on my hands when I used it on a picture of my Granddad, who is sadly no longer alive.Your browser cannot display PNG files. I took it in 1969 with an old black and white camera, but I was new to photography, and I moved the camera. Suddenly in the year 2000, I could see my Granddad's smile - in effect I now had a new photo of a man who died a quarter of a century ago.Not So Blurred Pic. I know it isn't perfect, the film in those days had bad contrast, but you can see his smile. Now with Unshake 1.4, I now have this;Relatively Good Pic.(I used "portrait" mode).

So that's why I'm enthusiastic about it, and why I'm offering it over the web; I do not have time to turn it into a sophisticated program, with all the bells and whistles which people expect of software nowadays, but I do want people to be able to use what I have, to rescue photographs of their own which matter to them. If anyone starts making money out of it, I feel I should get a cut, but I want ordinary people (I mean non-professionals, and those without access to much money) to be able to use it for nothing.

I met a traveller from an antique land
Who said: `Two vast and trunkless legs of stone
Stand in the desert. Near them, on the sand,
Half sunk, a shattered visage lies, whose frown,
And wrinkled lip, and sneer of cold command,
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
The hand that mocked them and the heart that fed.
And on the pedestal these words appear --
"My name is Ozymandias, king of kings:
Look on my works, ye Mighty, and despair!"
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away.'

Percy Bysshe Shelley
Why Ozymandias, why Hamangia?
