Sharpening blurred images

 

This is a very simple trick to sharpen efficiency blurred images.
I am using Photoshop Cs5 but this can be use in any previous version.

1- After open the image, create a layer by doing Ctrl+a   Ctrl+c   and   Ctrl+v 
2- Use the HighPass Filter
3- (Fig.1) Menu - Image - Adjustments - Curves.  Edit curves  and make a dot at 25% low and 25% of high

4-Stil in the curves

5- Menu - Image - Adjustments - Brightness and contrast
Add a little brightness (if necessary)  and much contrast

6- From the layer palette, apply the overlay

This is the result

Here, an other example for high pass filter
