How does a SLR camera make people feel blurred?

1 Use the shutter priority mode of the camera (TV mode, different cameras have different names, but the names are all shutter priority).

2 Set a lower shutter speed (such as 1/40s or slower), and set the focusing mode to real-time focusing (or servo focusing).

3 aim the camera at the target, focus and rotate the camera to keep the relative position of people in the camera viewfinder unchanged (this is the key). While rotating the camera, please press the shutter gently. In order to get the necessary effect, you must consciously press the shutter and then rotate it for a while before stopping.

So you can shoot the effect you want.

Another way: this is the advantage of SLR cameras. You can use a tripod to shoot still objects, or you can set a slow shutter. After focusing, turn the focusing ring, and then press the shutter in the process of turning, you can get a photo with a relatively clear subject and a blurred background.

The former method requires high technology. You can sit on the side of the road and shoot a car, which is faster.
