Panning cars

The constraint is implying speed — a car frozen at 1/1000 looks parked, so you deliberately blur the background instead. Set shutter priority to a slow 1/60, track the car smoothly as it passes, and fire mid-swing while continuing the motion, like following through on a golf swing. The subject stays sharp against streaked surroundings. ISO 100 and f/8 keep the exposure sane at that slow shutter in daylight, and continuous AF with tracking holds the moving car.

Watch out for a low keeper rate and jerky technique. Panning is a practised skill — expect to keep one frame in several, and shoot bursts to improve the odds. The blur comes from the background, not shake, so pan from the hips in one fluid arc and keep the car in the same spot of the frame throughout. If everything is sharp, go slower; if the car blurs too, your swing was not matching its speed.
