Thanks in advance

2) Select the particular part or the entire image which u need to blur.
3) Go to filter menu and select any kind of blur(i.e., Guassian blur,Motin Blur,etc)
4) The angle and ratio selection window will appear with a zoomed preview.Adjust it based on your necessity.
5)Press ok.

And save the image.

Your Blurred image is ready.
