What is the function of Huawei Glory X2 to add background blur when taking photos?

Background blur is to make the depth of field shallow and focus on the theme. If you want to blur the background, but the general DC does not have the function of large aperture, the camera can not achieve the effect of blurring the background. At present, the best virtual method in the smart phone industry is macro shooting, but it can also be realized by other methods.

The advantage of background blur is that if the smartphone can zoom, the zoom magnification is set to the maximum, which means that the background can be blurred to the maximum by shooting the image to the maximum. If the subject overflows the screen after increasing the zoom magnification, please ask the photographer to stand back and stay away from the subject. The larger the zoom magnification, the more obvious the blur effect. The aperture of some smart phones can't be set as a constant aperture. When the zoom factor increases, the aperture is shrinking, and the blur effect is not good.
