Skilled photographer, Kim

In fact, this kind of shooting, also called pop shooting, is to clear the subject, focus on the subject, and then use a slow shutter (usually 1/8 seconds). When the shutter is pressed, the zoom ring is rotated to change the focal length, forming a radial image centered on the subject. The zoom shooting mode can be changed from long focal length to short focal length, or from short focal length to long focal length, which can change the emission direction and get different effects.
