How to blur the shooting background?

1, large aperture shooting

The larger the aperture, the more obvious the blur. Although the aperture selection range of mobile phones is not as wide as that of cameras, it is generally around f0.95~f 16. Generally, we can control the aperture above f4, but it should be noted that the smaller the value, the larger the aperture and the more obvious the blur effect.

How to achieve the above goals with mobile phone shooting? Two ways. One is to use the photo function? Professional mode? , take the initiative to adjust it to a larger aperture; One was taken on a cell phone? Big aperture? Function.

Step 2 shoot away from the background

Under the same depth of field, the farther the background is from the subject, the more positions the subject occupies in the picture, and the more obvious the blurring effect of the background is. When we want to blur the background, we can move the mobile phone away from the subject and the background, or widen the distance between the subject and the background to achieve our ideal blurring effect.

Step 3 shoot near the foreground

One of them is imaged by lens? The shortest distance? When the actual distance between the subject and the lens is less than this? The shortest distance? Then the image is blurred. The camera is equipped with a special macro lens to solve this phenomenon. When we want to blur the foreground, we can artificially shorten the distance between the camera lens and the subject when shooting, so as to get the corresponding blurring effect.

4. Post-software processing

Some simple mobile apps can achieve the corresponding blurring effect, but this kind of software is relatively flat, mainly to solve the blurring of surrounding and specific elements, and it is impossible to distinguish foreground, subject and background.
