thats awesome! so high quality.. ive always wondered one thing, to make these pictures, are you using default textures on tracks or no? if not id like steal some textures off you :P
If I look at this picture I understand it as the camera would be traveling next to the object (car), same speed same direction. The camera is set up to capture a static car and a blurred/moving background, so why the hell would the wheels not necessarily have to appear blurred/spinning in the shot?
Also, who said parts of the car should be blurred when blurring the background? That's just a newcomers mistake.
Looks pretty nice, but what a shame the windscreen is not reflecting anything there on that bright shiny day.
