This is a photo that has been exposed to the end and is not by computer post-production overlay. Shooting method: studio+water stage+continuous light+flash+B shutter. I use the continuous light and slow shutter speed to capture the dancer's slow-motion hazy dance afterimage. Finally, freeze the dancer's clear motion with one-shot at a time, and take a photo with 10 seconds exposure. Shooting deliberately on the shallow water stage, the dancer Ending card uses a modern dance dress and long skirt to absorb water and kick the water with her feet.
