For people that shoot fast moving action with strobes like myself, we are always worrying about sync speeds and flash durations. Today I’m going to talk a little bit about flash sync and give a quick example of how you can push the boundaries of what can often seem like a very limiting factor with DSLRs.
One of the first questions people ask when they start experimenting with flash is “why does my camera not allow me to use a shutter speed higher than 1/xxx second?” If you scan through the specifications of a camera you will see one called x-sync. Typically listed as between 1/180 and 1/250 of a second, this is the fastest useable shutter speed of your camera when using flash. The best way to get to grips with it is to understand exactly what is happening in that split second after you press the shutter button.
