Step 1
Open up your image in PSP and go to ‘Effects’ > Blur > Motion Blur. This effect works better on objects/people who look as if they are moving (unlike my example!).
Step 2
Set the ‘Intensity’ to 40 pixels and click ‘Ok’.
Step 3
As your image will look messed up, click ‘Ctrl’ and ‘C’ (copy), ‘Ctrl’ and ‘Z’ (undo) and finally ‘Ctrl’ and ‘L’ (paste as new layer).
Step 4
Go to ‘Layers’ > ‘Properties’, change the ‘Opacity’ so it’s much lower and click ‘Ok’.
