In theory, yes. In practice, not necessarily very well.

Well, something like http://www.hamangia.freeserve.co.uk/ might help a bit.

Can the dead be brought back to life?

Actually, if its not too bad, you can sometimes fix it enough to fool the eye. Focus Magic has helped me a few times, especially the motion blur utility. It will never be 'right'.

Shoot the photos again, this time be careful.

Yeah I suppose I asked for that, but anyway thanks for those that were helpful.

The answer is YES
You need access to high level (proprietry/military?) software though !

I saw a demo of this on the UK TV program 'Tomorrows World' a few years ago - a bluured image of a cyclist taken against a stationary background. There is apparently software that can compare different parts of the image and apply correction to the stuff thats blurred from the known stationary material in the image. The demo I saw was stunning... I havemt heard anything of it since..

Back in the day, I used to spend a lot of time doing software demos for trade shows and the like.

You can do some really, really stunning, amazing, unbelievable things in a software demo...by choosing your demo images very, very carefully, and setting up everything so that it's absolutely optimal for your particular software. Real-world performance, on the other hand...not usually so impressive.

Fixing motion blur in an otherwise sharp image is a different task than fixing an image that is out of focus. With motion blur, if you have a high bit-depth image, you can do a fast Fourier transform on the image, find the parts that stand out, and apply localized correction to them--having a 16-bit-per-channel image (or higher) really helps with that. An out-of-focus, probably JPEG-compressed image from a consumer digital camera, on the other hand, is a whole 'nother can of worms...

Always the same with everything on TW, It's like when we were kids and they started building nuclear power stations, electricity was going to be free and we'd all be flying around with jet packs. So where's my bloody jet pack???

LOL

You've watched too many episodes of CSI.

Ok, what's been said in this topic is true: actually you can't focus an image that it's out of focus. What you can do is SIMULATE the effect of focus by choosing Filter>Sharpen>UnsharpMask or Smart Sharpen. What this command does is to add more contrast on the "borders"of the image , that is where there are color changes.

Hope this helps

Er no I haven't - I can't stand american TV shows!

The stuff I Saw on TW was real enough and there were several examples of recovering information in a wide variety of blurred images... I can't imagine that this stuff isnt easy these days. We can actively correct image blur by using laser guide stars in the Active and adaptive Optics systems I am familiar with - the US military was doing this 20 odd years ago and its now in the public domain... Just need a Windows version of whatever it is !!!! ....
BTW - I do have my jet pack - I use it every day!!

So, you're one of those guys that made me buy xyz software, huh???!

That last sentence shows flair in understatement....

You can give the appearance of the image being more in focus than it is by shrinking it, and applying USM, where your mileage will be all over the map....
