Set the distance to around 40 pixels,
and then adjust the angle of the blur
until it??™s roughly in line with the
direction of the subject??™s motion.
4. I??™ve added blur, but unfortunately,
it just looks, well, blurry. It??™s as if
someone bumped into me right as I
took the picture. Use the Eraser to
fine-tune the blur. Click the Eraser
tool, which does just what it sounds like??”it erases pixels from the picture. But since you
have the original image in the layer underneath, the Eraser will let you combine blurry
and nonblurry sections of the picture by revealing pixels from underneath.
5. Set the Opacity to 100 and adjust the size of the eraser, if necessary, so you don??™t wipe
away too much of the picture with each stroke.

6. In my case, I use the Eraser to
sharpen the leading edges of the
plane??”the nose, the wings, and
the tail section??”and sharpen
the inner sections of the body
as well, leaving just the trailing
edges blurred. My final image
looks something like this:
Blur the Background
That??™s one way to add motion blur to an
image. It??™s akin to keeping the camera
stationary while you snap a picture of a
moving subject. Another technique you
might want to try is akin to panning (see Chapter 7).
