I will be doing one of those shots where I (cameraman) will be on the side of the road, focusing on an oncoming car. As the car gets closer, I will pan so that the passenger becomes a tight close up, and then continue to pan as the car drives away. Anybody who's ever tried this shot knows it's extremely difficult as you have to exponentially speed up the pan as the subject gets closer. It's very important that my close-up is in the center of the frame as I will probably slow the shot down in post. Anybody have any advice to make this shot easier?
