Remove motion/still blur from Images using Adobe photoshop

Recently,i required to rectify an image which i had taken during my training.And while trying to do so,i ended up learning this method which i s very helpful.
Tool used for this,is Adobe Photoshop.

Initial picture/image being used :

*click the image to zoom in.

  • Step 1 : adjusting the tilt of the image according to the desirability.Also used for selecting the required portion of image i.e. cropping.
use the crop tool,select the image then take the pointer outside and tilt/rotate.
*Notice the area as the border around the image ,as its removed in the next image.




  • Step 2: Image Rectification Starts now.Firstly we need to clear the Localized noise.
so select " Filter -> noise -> dust and scratches",from the menu bar.
now set the "radius = 1 " and "threshold = 0 ",and preview the image portion.click "ok" to apply.
you won't notice a great difference but its a necessary step.comparative image would be somewhat like this:



  • Step 3:Go to "Filters -> blur -> gaussian blur "
keep the radius pixel betwwen .2 to .5 to have best results.preview and click "ok".
image would be something like this:


  • Step 4: Go to "Filters -> sharpen -> unsharp mask "
keep the "amount between 25 to 33 % "
keep " radius between 2 to 4 pixels "
keep "threshold =0 "
image is ready for final touch,it should be something like this :


  • Step 5:go to "image -> adjustments -> auto contrast "
this sets the contrast level automatically to match normal view.Image is finalized and ready for work.

The Results do vary from case to case.Also have used a good scanned copy for example so Differences are not too noticeable ,but it will definitely help you in the time of need.
The Photoshop version used by me is 7.0 and CS2 is said be a better version,so update will come soon,may be with a better example.
