Blurred foreground, blurred background, how to take a photo with the focus in the middle?

Turn up the aperture a little and expose the focus to the background. If the camera has manual function, please use manual exposure. If not, please use aperture first.

In photography, this is called blurring the foreground. In fact, the principle of blurring the background is the same: when the camera lens images, there is a range to obtain a clear image (the technical term is depth of field), which is generally centered on the focus of the focus and extends back and forth. The specific depth of field is related to the focal length of the lens and the aperture value when shooting. Under a certain lens, the larger the aperture, the smaller the depth of field.

To sum up, in order to get the desired effect, we should try to open the aperture as large as possible (you can use manual mode or aperture priority mode), and then expose it to the background, so that the foreground will be blurred.
