Wow Rangerman thats an amazing capture of an F1 car, probably one of the best I have seen.
I have a few questions, what was your setup to get this, lens, body and settings. Probably the sharpest panning shot I have ever seen, almost like the car was actually sitting still with a radial blur applied to the tyres, shopped onto a another still shot of a track with motion blur applied.
As they say, get it right in camera.
Why does the front tyre on the rumble strip look like its at about 50% opacity, same with the mirror area on the same side, is that some sort of optical illusion, I cant for the life of me think how that could happen if the car was essentially in the same place in the frame for the duration of the pan and still have the car itself sharp?
So many questions, but I am sure you will have some really great answers or perhaps someone else could clarify for me, I would love to able to get an image like this myself.
