Not to easy. Action photography using a tilt shift and remote flash. Luckily we got 'tripods' and bubble levels to get everything straight to start with. Used the Pocketwizard Mini TT1 and Flex TT5 to fire the remote flash on the bikers.
Using the PC-e 24mm tilt shift lens I maneged to tilt the focal plane in such a way that the bikers in the background and the track in the foreground are both in focus. Due to this change in focalplane direction, the sharpness of the image falls of to the sides.
For the last image I stitched three horizontal images to a vertical panorama. I used the shift function of the tilt shift lens to get the three images without perspective problems. Using this method I turned the Nikon D3s into a 22MP camera.
