Video photography, with clear characters and blurred background, is how to shoot. I use a Sony camera. The picture was cut from the video.

I don't know what kind of Sony camera you use, but I use a small FDX-30 4K camera with a manual function adjustment ring in front of the lens. If you want to shoot the blur effect of shallow depth of field background, you should first fix the aperture at the maximum or maximum level, such as F 1.8 or 2.0, and then assign the manual focus to the manual function ring, because the camera speed is around 1/60. I use an adjustable ND2-400, so I can get the effect on the screen, but the fuzzy effect is not as virtual as the background on the screen. After all, the camera is a zoom lens with a small aperture.
