This tutorial is based on the assumption that you are at almost right angles to the automobile, looking straight at the side. I will do a much more complicated tutorial on how to create the same effect on a car that is at an angle to you, at a later date.

Okay, so you have taken the perfect picture in GT4 and gotten the car and background blurred as you desired. The problem is, is that it looks like the wheels are all but motionless. After all, the car ads show the car in perfect clarity but with rapidly spinning wheels. Right?
Well, since you don't have a camera car to follow alongside of the car in question, going the same speed, I will show you a REALLY simple way to get the same effect in just seconds in Photoshop.

One thing that I need to point out about all of my tutorials, is that I am a PC Photoshop power-user. That means I use a LOT of shortcut keys to speed up the work flow. I will make note of them when they are used so that, if nothing else, you will learn a few of them by the end of the tutorial. :)

1) Let's start with our unaltered image below. I have made it in to a link so you can copy it to your system if you wish.

2) Start off by zooming in on the first of the two wheels.

3) Now we need to select just the wheel and tire of the car.

4) Now that we have our selection, we can apply the proper motion blur.

... which brings up the window below.

5) Once you are satisfied with the results, select the other tire with the marquee as in step 3.

Now if you like, you could change things up a bit and have the drive wheels, the ones pushing/pulling the car, spin faster to give the effect of a burnout or loss of traction. It is all up to you.

Here is the completed "after" picture with both wheels done at the same amount. Before and After.

I hope that this has been helpful to you, and that it will make your shots all the more exciting. Good luck and happy Photoshopping!
