In the Layers Palette I placed Image 1 above Image 2. Next I opened up the Channels palette and selected the Distance channel - using the magic wand tool (using a tolerance of 12) selected the foreground vehicle silhoette. Then gone back into the layers, with the selection still highlighted, to cut the foreground racer from Image 1 and paste it into a new layer. Once that's completed can I finally merge Image 1 into Image 2. Now the red racer won't have any of those 'faded' streaks around it once I apply the blur effects.
