Taken whilst sat in the passenger seat of my friends car I saw this on the back of a trailer, reached around grabbed my camera bag and selected Fully Auto settings. The image initially showed me in the refelction of the wing mirror and straps holding the wheels in place.
Changes made:
Levels
Auto Colour
Motion Blur Back ground
Cloned out the strap over the wheels
Radial motion blur in the wheel
Dodged the wheel nut to enhance the motion in the wheel itself ( although not actually present )
