I really think of the airport as a studio. Isn't it embarrassing for a star to shoot like this?

No, the key to live capture is the shutter speed.

Using zoom lens, the maximum aperture value is of course the bigger the better.

ISO is set to 800 or 1600.

First gear, the aperture is fully open to the maximum. Shoot the shutter for at least 1/250 seconds, so that the shot image is clear.

Continuous shooting model.

When taking a snapshot, the subject is placed in the center of the picture. It's better to have a flip screen, which is convenient for you to compose the picture when you lift the camera to capture it.

If possible, you can use an external flash.
