In the studio, use a tripod and a 10-second long exposure shutter, plus the first half of the continuous light to create a dynamic moving afterimage, and finally use the flash to freeze the clear ending card of the ballerina. This completes a dynamic ballet photo. The photos are taken in one shot. No post-production overlays. Moving photos, apart from recording the process of ballet dance performances, also make the visual images indistinguishable from reality and reality.
