Second-curtain sync with Speedlites

Many photographers are familiar with the effect of second-curtain sync (the flash is triggered just before the camera shutter closes meaning that, when using slow shutter speeds, the subject is followed by a light trail recorded with ambient light) but not how to make it work. To enable second-curtain sync press the ‘High-Speed sync/Shutter curtain synchronization button’ so that the Triple Forward Arrow symbol is displayed. Press again to return to normal mode. Alternatively, in the camera Custom Functions choose ‘Second-Curtain synchronization’ (C.FN II -5-1 on EOS-1 Mark III series cameras).
