Second-Curtain Sync - Canon MACRO RING LITE MR-14EX II Mode D'emploi

r Second-curtain SyncN
Shooting with a slow shutter speed and second-curtain sync captures
the trajectory of the light source of a moving subject in a natural way.
The flash fires right before the exposure finishes (shutter closes).
Second-curtain sync works well when the camera's shooting mode is set
to <F> (bulb shooting).
To return to normal flash shooting, press function button 4 <Y> to
turn off <r>.
When the flash mode is set to <a>, the flash fires twice. The first
flash is a preflash to determine the flash output. It is not a malfunction.
Second-curtain sync is disabled during wireless multiple flash shooting
(p.44).
