How do i create this effect?

In fact, very easily
Just use a fast shutter speed as 1/250-1/500 (or lower if you want to increase the effect) and just track the car with the camera, doing a panning, and keeping the car "static" in the frame, while you press the shutter button. This way the car is "stopped" in the frame but the background is actually moving at the car speed, so using a intermediate shutter speed, you motion blur the background but not the car.

Yes,. it is called "panning"

Two ways, old school and new age.

Panning at slower shutter speeds, depending on technique and skill, you can pan down to 1/30th and even use a flash.

Do it in your digital dark room. But that's cheating to a purist.

And of course you'll need a Clio too

Like the rest of the group says panning, go out to a busy road & practice its fun with people running or on bike also.

Not sooo easy. Keeping a fast moving car in frame on a 400mm lense is a skill learnt through hundreds of failures.

Not 'easily', but with a lot of practice to get the panning technique right. You need to shoot with a fairly slow shutter speed, start at 1/250 and work your way to slower speeds as you get better.

For example, this panned shot was taken at 1/125

Both awesome shots Kenny that I would die and go to heaven if I managed. Just the right degree of blur to convey a feeling of speed.

wow, those are wonderful shots kenny.

thanks you guys for your advise, i think ill go camp out by the side of the street today and give it a try!

A monopod is surely needed to achieve a nice panning effect. Am I right? I haven't tried it yet but I sure like to try it someday.

KennyG- fantastic shots!
Let me ask a question: would it be wise for this type of a shot to actually set up a tripod with horizontal degree of freedom only- in other words, your camera can rotate gorizontally freely, but not up and down. Set it up in advance and practice with a couple of cars to get a movement of a tripod head in sinc with cars.
Does this sound like something usefull?

This looks more like PS motion blur than the 'real thing'.

Using a static picture of the car, select the car, select inverse and apply motion blur to the desired level (don't forget little areas like windows etc)

Then select each wheel in turn and apply radial blur. Finally, rotate to give the hill effect and crop to taste.

Although PS gives the flavour of motion, I feel it lacks something achieved by using the photographic panning technique. Although some of the experienced action photographers have said this is easy, I have yet to master this skill to achieve a sharp car image. However, the 10D is the perfect tool to practice with - quick feedback at zero cost!!

I think it would be quicker and easier to make a panned picture of a car than to try and make a believable, simulated pic in Photoshop. Just because the picture makes the car look like it's going fast doesn't mean that it is. If the shot is a setup, have the driver go 10-15mph and use an appropriate shutter speed. You may have to experiment with different shutter speeds to get the best effect.

No, panning like this is best done hand-held. You need the freedom to track the car, selecting it as it comes into sight, take the shot at the appropriate time and make sure you follow through. You just can't do this with a tripod, far too restrictive. You get into a rythm as you take panned shots on a race track, with your feet still and your body swivelling at the waist you develop a flowing motion like a golfer practicing swings.

A monopod is only useful for panning when you are using really big glass (my 300mm or 500mm primes for example) where hand-holding isn't practical. Even then it depends on where you shoot from on the track as to how good a 'swing' you can get with the lens on the monopod.

It is all about conveying motion and speed. If you are in a position to get good panned shots when the track is wet, then you have an opportunity for a bit of experimentation, as here:
