Rear shutter curtain sync

April 08 17:21 2017

By default most cameras are set to front curtain sync which means that if the flash fires, it does so at the beginning of the exposure time. By setting to rear shutter curtain sync it fires the flash at the end of the exposure time. The difference in some cases me be negligible, but in shooting a moving subject front sync will put any motion blur in front of the subject, where as rear sync will place the blur behind the subject. Neither is wrong, just preference.
