The car was coming around the bend at 110km/h, I was laying on the ground about 25 meters away. The Pocket Wizards (set on TTL) allowed me to use a very high shutter speed of 1/640s to fill the car with the two speed lights in their soft boxes. The light from the right is the soft rays of the rising sun.
I was in another vehicle with an assistant. He had a boom with a speed-light attached to it to light the front of the car, while I shot it a low shutter speed of 1/125s to get the feeling of momentum on the road and in the wheels of the Golf.
