For many, many years photojournalists have been using a technique called the Flash and slash–but it can easily be mistaken for sloppy work by the untrained eye. But as told by the folks at Ultimate Photo Guide, it isn’t a mistake and instead just a creative trick to show emphasized motion.
The flash and slash technique involves the use of flash and second curtain sync. It’s used to dramatize movement while keeping a single subject perfectly sharp in the frame. Photojournalists tend to use it with panning or turning their camera in some way or another. In fact, it’s a very highly used technique during very high profile and chaotic events. Sometimes it’s even used in sports.
