This is a cool effect that was inspired by the "Prodigy: Fat of the land" CD cover... Basically it makes the image look like its moving towards you...
Pick out your favorite picture, (i.e. a car, an animal...) Make sure the image is in RGB mode. You can check by clicking on Image and then Mode.
First, make a selection around the area of the image you want to keep clear.
Then, make a quick mask (Press Q)
Apply a gaussian blur arounr 13 or 14 for large images, choose 9 or 10 for small images. In this tutorial, I used 10 pixels. Click OK.
Now use the Sprayed Strokes filter (Filers -> Brush Strokes> Sprayed Strokes). Use the standard settings:
Stroke length 12,
Spray radius. 7
Stroke direction: Right diagonal
Click OK.
Now go back to Standard edit mode.
Inverse your selection. (Select -> Inverse selection.).
Apply a Radial Blur (Blur method: zoom, amount 40) , and there you go!
The end result!
