Measured
in fractions of a second.

•WHAT
IS SLOW SYNC FLASH?
•Slow sync
flash is just a fancy term for using your flash with a slow shutter speed. It
helps you keep your subject sharp while capturing motion or a dark background.
That's it. Simple, isn't it?
•You
see, with a normal flash photo, the shutter is only open for a fraction of a
second, so the flash is firing for most of your exposure.
•With
a long exposure, your camera's shutter is open for much longer than the flash
is firing - perhaps even several seconds.
•You can
choose whether you want to fire the flash at the start or end of the exposure.
•Firing
the
flash at the start of the exposure is known as "front curtain" or
"1st curtain". Firing it at the end is known as "rear
curtain"
