Flash Duration.The shorter the flash duration, the better. This is very im-
portant when shooting outdoors. Durations of^1 / 1300 second or more are great.
This is important when capturing moving objects or action when utilizing
short shutter speeds outdoors, thus providing for a higher dynamic range
when intermixing daylight with flash and better flash synchronization. Long
flash durations will continue firing while the camera shutter has already closed.
This often causes a color shift toward the blue spectrum and also can cause un-
sharp images.
