How to take this photo!

1, what people can do when they are moving, camera positioning, shooting both, one that has not been exposed for a long time and one that has been exposed for a short time (stop moving the aperture), and then someone is at the bottom, the last version of PS, and the characters are erased with an eraser, which is basically invisible.

2. Apply ND to extend the exposure time and synchronize the front curtain. (It's easier to control than Hou Lian, so you can leave after flashing, and you have enough time to put on the action, and then the curtain is in a hurry). You can also expose door B for a long time and then give people strong light.

3, increase the depth of field, or synchronous movement, such as walking in the car, tandem, driving.

Generally speaking, the first one is recommended, and the second one is very difficult to operate in practice, and the image quality is obviously degraded, so it is not easy to take care of both, and the flash is artificial light after all.
