JAMES’S comment

We started off shooting cars coming straight at us at Luffield Corner. I shot in Tv mode, and set the ISO at 640 for a fast shutter speed of 1/1000 sec, to freeze the car for a sharp shot. First I tried using AI Servo AF to follow-focus the cars, but then Jakob helped me use back-button focusing to pre-focus on the track, and I quickly got better results like this one! Jakob also explained how to use the Rule of Thirds for balanced composition, which makes sense when you think an image is 3:2 ratio.
