The Motion Blur Filter
Selection 1 Preparation:
Using Motion Blur effectively takes a little preparation. Used straight on an image, it creates a loss of detail, or merely replicates the effect of camera shake. In this image, we want to preserve detail while creating a feeling of rapid motion.
2 Selection:
To start, make a feathered selection of the rear half of the girl. A Feather setting of about 6 pixels should be sufficient for a lowresolution shot, but you need to use higher values for high-resolution images.
Finish a "quick and dirty" selection -- the blur effect means that accuracy isn't vital -- then press
Ctrl/Cmd + J to copy and paste it to a new layer.
Call the new layer "copied selection."

3 Now Blur Keep the copied selection layer active and go to
Filter > Blur > Motion Blur. Set the angle to 0 degrees and the distance to 90 pixels.
Motion Blur
Make sure the Move tool is selected, then press the right arrow key on the keyboard about 12 times
to move the selection to the right.
This gives the impression that the girl is leaving a blur of movement in her wake.
For a stronger effect, merely duplicate the copied selection layer.
Duplicate the layer
TIP Blurring with Blend Modes
After duplicating the copied selection layer, try changing the blend mode of the top version to Lighten.
This produces an almost ghostly effect.
Here are the results
