Extended information:

The principle of camera rear curtain synchronization:

Rear curtain synchronization is a slow synchronization, and flash is used when shooting portraits of people in night scenes. Ensure the correct exposure of the characters, and then use a slow shutter speed to ensure the correct exposure of the night background. When the shutter is open, the flash does not emit light, so the subject is underexposed at this time (of course, if the illumination is too low, the image will not be left on the film), but the film can still record the underexposed image. , and the subject is in motion, so what is recorded on the film is a smear.
