This can't be straight off the camera. But I have no idea how to achieve this extreme motion blur in photoshop. The regular motion blur filter doesn't seem to be cutting it.
Well I understand shutter speed for rolling shots, but to me, it seems near impossible to keep the car that sharp while holding the shutter open for a long enough period of time to get that extreme of a blur. Seems like the car would at least be a little blurred from the camera vehicle hitting a bump in the road, or something.usually they just set the camera to open the lens for a longer time, and set the lens opening size really low so that way the lens will open for a longer time allowing the camera to capture movement but because its only opening a small diameter the picture wont come out too bright.
And then they just roll at the same speed as the car being pictured and hold the camera steady for the picture.
I dont know if that made sense, its hard to explain.
