Second-Curtain Sync - Canon SPEEDLITE 600EX-RT Manual De Instrucciones

r Second-curtain Sync
Shooting with a slow shutter speed and second-curtain sync captures
the trajectory of moving light sources, such as car lights, 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 "buLb".
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. This first
flash is a preflash to determine the flash output. It is not a malfunction.
Second-curtain sync is not available during wireless flash shooting.
