I came across software called “Focus magic”. Tried in on one of my shots I took 2 weeks back. The result is pretty impressive. You can make not so sharp pictures look sharp by using this
Cropped version for comparison. If you check the eyes on the before and after pics the change in sharpness is clearly visible.
The steps are very simple
1. Load the image
2. Choose the filter option to focus
3. select Blur width and Amount as per requirement
4. Hit the process button
One thing to note is, if you press save, it just saves the processed version to the same file. So make sure that you are always working on a copy.
This is another sample which i processed just now.
