Light trails
How I shoot headlight trails at a night race.
- Lock the camera: tripod, wall, fence. The slightest shake ruins the shot.
- Slow shutter, 1 to 2.5 seconds: long enough for the lights to draw the whole corner.
- ISO 100 and a closed aperture (f/8, f/9): clean blacks, sharp from kerb to grandstand.
- Press the shutter when the headlights enter the frame.
