Flash Duration Measurements
Understanding flash duration is the first step in freezing fast-moving subjects. Since all cameras are limited to relatively low sync speeds, stopping motion in a single image is often achieved by leveraging short flash durations with the camera’s max sync speed. A long-held secret of some of the world’s most talented photographers, the key to freezing action consistently is found in being able to measure flash duration. Photographers are now able to do this easily for the first time, demystifying one of photography’s most challenging techniques.
