Master photographer, help me see the effect of this photo.

Can I shoot with a normal headgear? -In theory, but I'm afraid it won't work in practice. It's almost impossible to shoot this effect.

This is a shooting technique! It takes a certain amount of exploration and experience to get used to it.

Briefly explain: first, you should use the slow door 1 sec ~1/8 sec or even the b door, otherwise there is no way to operate (there is no allowed operating time);

Second, use a zoom lens. When taking a view (the moment when the shutter is pressed), you should take a view according to the required center and size of the picture. When the door is open and not closed, zoom quickly, from the initial focal length (for example, 50mm) to the wide-angle end (fast and uniform zoom without stagnation) until the shutter closes.

This really needs a lot of experiments to accumulate experience.

At this time, a shooting technique gives the picture an "explosion" feeling, which has a strong effect of highlighting the center! In the past, it was often used for emergencies, sports photography, humanities documentary and other topics.
