I'm fairly new to this stuff but this is a good challenge. I believe in a few years this will be possible, so save the image. In the mean time, here are a couple attempts.
Great idea on the "drawn" version! This is a good way to salvage the pic

How did you do that. It is much better.

Of course the image has the trial stamped all over it. And without the original the photo to work with was a small thumbshot.

Those de-blur programs can do a LITTLE bit of correction to SMALL amounts of blur. This one is beyond repair.
Ditto!

14 yrs ago at my wedding the pics I had taken with my family (film pics by professional photographer) were blurry. The photographer after apologizing explained that they couldn't be fixed. I tried different places to no vail.So now when I take a pic, specially family pics, always snap a few and then pic the best. sorry i couldn't offer better advice.

Does anyone know if its possible to unblur a photo at all?

You of course know why it's blurred correct? camera movement.
No it can't be done. You can sharpen it a bit but you'll not get rid of the blur.
Sorry.

Hi .... i just played ...... another version -- a little better i hope ....
perhaps ....

I saw a video not too long ago about something Photoshop was working on and it might be able to fix this. But for now nope.

Camera movement blur is easiest to correct for. Photoshop Elements has a feature in sharpening to do it. I'm moving to Photoshop and haven't found it there yet but if I do might give it a go.
I think this is out of focus blur, though.

I sharpened first in Lightroom and then tried Blurity. It seemed to work best with the box around the woman's head and minimial deblur.
Not what you'd call "tack sharp" but significantly improved.
It's probably worth buying the program if you want to fix it. It's $39.

With Lightroom sharpening first
Without Lightroom first

I think it depends on why the photo is blurry.
The blur can be caused by camera shake or it can be out of focus or it can be caused by both together.
I studied electrical engineering at uni many moons ago and some of the fancy maths we learned seems applicable to this problem, particularly if the blur is only the result of bad focus with no shake. The use of a lens is equivalent to a two dimensional Fourier transform being performed. If the blurry image is convolved (A special mathematical operation that is related to Fourier and Laplace transforms)with the transform of a lens differently placed to the lens that took the blurry photo, then it should be possible to refocus the image. Its a bit like being able to put spectacles on the original camera to get the picture in-focus. The out of focus image still contains all the information necessary to refocus it. I recall seeing the results of this refocusing in around 1973 when the necessary computer resource was hard to come by and expensive, similar to that needed to do the Fourier processing for a CAT scan - half an hr on an IBM360. Now of course everyone's home PC is fifty thousand times faster than that IBM. It is possible that some of the computer programs mentioned may be doing this. If the blur is due to camera shake this process wont work, but the human eye can often see which way the camera has shaken and so it might be possible for a smart program to do the same.
Hope this is of interest and everyone can understand my half-garbled account.

I understand. There is software today that does that for military purposes. The major photo developers are on to that approach. A link to one was posted in UHH a couple of months back. I didn't save it but it was looking pretty good under certain circumsances.
Camera movement is relatively easy to account for. There is even a feature in Photoshop Elements 10 to try. Subject movement is more difficult.
I believe that program Blurity is based on the fourier transform approach. They calculate a "kernal" and use it to adjust the rest of the photo. With Blurity you put a selector on a portion of the image you want it to use to calculate the kernal.

Hope you don't mind that I played with this. I'm fairly new at Photoshop, so it looked like something I could practice with.

Hey, that worked quite well
