Im trying to motion-blur the background on an automotive photo I shot and didnt slow the shutterspeed down enough. So, using the quick selection tool, I selected the car, zooming it in to make sure I got every pixel, then Cntrl-C, then Cntrl-V to save as a layer. Then, I reselected the background layer and applied motion-blur which got me the effect I want. The problem is now the edges of the car have a ghost outline which will decrease if I lessen the blur to under 12 pixels. Which defeats the purpose. Am I missing a step here, or is this as good as it gets? Im using CS4 by the way. Thank you so much for anyones help.
