Pentax K20D manual 140, Using Trailing Curtain Sync

140

Using Trailing Curtain Sync

Trailing curtain sync discharges the flash immediately before the shutter curtain closes. When shooting moving objects with a slow shutter speed, Trailing curtain sync and Slow-speed sync produce different effects depending on when the flash is discharged.

For example, when shooting a moving car with Trailing curtain sync, trailing light is captured while the shutter is open and the flash captures the car immediately before the shutter is closed. Therefore, the picture will include a sharp, well-lit car with trailing lights behind it.
