how can i fix this picture?

I think there is a misconception that you can fix images later by using Photoshop.

The rule advanced amateurs and professionals use is "get it right before pressing the shutter release" The only post production necessary should be processing the RAW images, merging panoramic photos, converting to black and white and producing HDR images from a series if images.

Did you take the photo? If not, only the actual photographer has the rights to make changes in it or you have to have written permission from them.

Blur is caused by movement. What you are calling blur is actually out of focus areas of the image and that is caused by not using the correct lens aperture to keep the important parts of the subject in apparent focus.

There are really only a couple of choices.

* Reshoot your friend making sure that the important parts of her are in focus (stop the lens down)
* If you do any retouching, make sure that you make a copy of the original image file and work on it. The best way would be to shoot in RAW and after processing, export it as a TIFF file. TIFF files do not degrade each time you save any changes in them. Once you have finished with the Tiff file, you can save it as a high quality JPEG.
* Hire a professional retoucher to make the necessary changes.

Just like photography, retouchers spend a lot of time taking classes and more time honing the skills they learned in class. Most good ones have also worked for a pro photographer or retoucher for a few years.
