How do I use my phone to blur the background?

You can turn on the Meitu App on your phone. Select the bokeh person in the camera. Aim at what you're trying to shoot and he'll automatically focus. The background will blur and blur.

If you want to use your phone to capture a blurred background effect, you can use the wide aperture in the camera. The camera's wide aperture blurs the background and accentuates the main point.

Use the focus function. Turn on the focus function of the phone and fix the focus on an object so that the background will blur.

The phone's large aperture mode can effectively complete the effect of background blur, just pay attention to the way you shoot.

The clear background blur of the character is the background blur function of the mobile phone, which can highlight the theme and blur unnecessary backgrounds. Here are the specific steps on how to take a picture of bokeh with your phone:

1.Turn on the camera function on your phone, enter the photo interface, you can see the large aperture mode icon at the top of the interface, click to open.

2.When selected, the wide aperture mode is turned on. The interface will remind you that "it is recommended that the distance between the camera and the subject be no more than two meters", so that the background blur effect will be more obvious.

3.Move on the screen to select the focus, click the focus circle, the right side of the slider appears up and down, you can adjust the size of the blur by sliding the slider.

4.Click to take a photo, and you can take a beautiful background blur**.

Here's how: The blur effect is also the effect of blurring.

1. First turn on your camera, the camera that comes with the phone is fine.

2. First of all, let's introduce the autofocus to blur the background, if it is automatic, click on the object on the camera you want to shoot clearly, and the camera can autofocus, and the effect is better if you are close to the object.

3. Take an object in the background as a reference, so that the focusing effect is better than the blank background. These are relatively simple autofocuses. Let's talk about manual focus.

The background of the shot is blurred, and the subject is clear**. Mobile: Huawei P30

System: EMUI

Software: Local settings.

1. On the desktop of your phone, tap Camera. and high tremor.

2. Then select [Large Aperture].

3. Click on the icon pointed by the arrow on the right.

4. Start adjusting the size of the cursor.

5. Swipe left is to make it smaller, swipe right to make it bigger, the smaller the cursor, the higher the background blurred Chengdu is, and the lower the reflexive pickup.

Some. It's just that it's hard to judge whether the effect can reach the level you require.

At present, the shooting module lenses of high-end mobile phones are relatively strong, and the main cameras are all large-aperture and high-resolution lenses. It is possible to shoot with a shallow depth of field**. Sony's shooting module, for example, has such a function.

High-end models such as Xiaomi and Redmi can shoot the effect of shallow depth of field. In addition, flagship models of brands such as Huawei, OPPO Reno, and vivo are also available. If the requirements are not high, there is no need for post-processing.

1. No. The bokeh of mobile phone imaging is all Gaussian blur software processing, and the quality of Gaussian blur is determined by AI intelligence, and the mobile phone cannot achieve the shallow depth of field (bokeh) of physical imaging;

2. The bokeh ability is determined by the focal length, aperture, subject distance and diffusion circle diameter. The four elements involved in blurring complement each other, and as long as one of them becomes weaker, the blurring ability will decrease;

3. Focal length. The focal length of the lens is physical, fixed, and does not change. Lenses with the same focal length are mounted on sensors with different areas, and the imaging angle is different.

For lenses with the same focal length, the larger the sensor area, the wider the viewing angle, and the smaller the sensor area, the more load the viewing angle, this change in viewing angle is called "equivalent focal length" (there is a formula to calculate). But no matter how the angle of view is equivalent, the focal length of the lens is always the same. That is, the equivalent focal length only affects the angle of view and does not change the focal length.

At the same viewing angle, the larger the sensor area, the longer the lens focal length, and the smaller the sensor area, the shorter the lens focal length. The longer the focal length of the lens, the stronger the bokeh, and vice versa.

4. Aperture. Aperture is also a physical property that does not change and does not change with the area of the sensor. The larger the aperture of the lens, the stronger the bokeh, and vice versa;

5. Subject distance. The subject distance consists of two parts, one is the distance between the lens and the subject, the closer the distance, the stronger the bokeh, and vice versa; One is the distance from the subject to the distant background, the farther the distance, the stronger the blur, and vice versa;

6. The diameter of the diffusion circle. The larger the area of the sensor, the larger the diameter of the dispersion circle, the stronger the bokeh, and vice versa.

7. In the ratio of focal length, aperture, subject distance and diffusion circle diameter (depth of field calculation formula), the proportion of focal length, aperture and subject distance is relatively high, and the proportion of diffusion circle diameter is very small, so small that it can be ignored, so the diameter of the diffusion circle can be ignored. But in a rigorous sense, the diameter of the diffuse circle still affects the blur. Therefore, bokeh = long focal length + wide aperture + close subject distance.

8. The aperture of the mobile phone can be made relatively large (the subject distance is affected by the environment), but the focal length of the lens of the mobile phone is very short. Because the sensor area of the mobile phone is very small, generally 1 3 inches (there are also 2 3 inches or 1 inches), the equivalent angle of view coefficient of the 1 3-inch sensor is , therefore, the focal length of the mobile phone lens can only be very short. For example, with the same 76° angle of view (28mm lens angle), the lens focal length of a full-frame camera is 28mm, while the lens focal length of a mobile phone is only .

Assuming that under the premise that the aperture and subject distance are the same (the proportion of the diameter of the diffuse circle is ignored), the focal length of the mobile phone lens is too short, and the shallow depth of field effect cannot be created. Of course, the mobile phone lens can also be designed to be longer, but due to the influence of the sensor area, the focal length will be narrower when the focal length is longer, and the mobile phone will become a telescope, and the use value will be greatly reduced.

If you don't want to be bokeh obtained by post-processing, then you can only shoot at close range, because the bokeh effect is related to the focal length of the lens, the aperture and the position of the shooting space, simply put, the longer the focal length, the larger the aperture, and the closer the distance, the more obvious the bokeh. Although the aperture of the lens of mobile phones is generally relatively large, due to the size of the sensor, the actual focal length of the lens is relatively short, so it is difficult to have an obvious bokeh effect unless you shoot at close range. Therefore, it is still possible to blur some small objects, but if you shoot people, there is no good way, and you can only rely on post-processing.

The sensor size is too small for physical limitations.

The operation method of taking a picture background blur without a smart machine is as follows:

Tools: Xiaomi Mi 11, MIUI12, Albums.

1. After unlocking the phone first, turn on the camera as shown in the figure below.

2. Then in the page that opens, click on the manual mode below.

3. Then click on the focus option, as shown in the image below.

4. At this time, the focus can be adjusted to form a background blur effect, as shown in the figure below.

5. After the installation is completed, the photo is completed.

To use your phone to capture a person's clear background blur, you can try the following solutions:1Use a phone's camera with a bokeh background:

Nowadays, many mobile phones have a bokeh background function, which can be taken by selecting "Portrait mode" or "bokeh background mode" in camera mode. 2.Manually adjust the focal length:

Use a phone that supports manual focus to achieve a bokeh effect by adjusting the focal length while shooting. In general, the background can be blurred by focusing on the person, moving the background away from the person, and using a wide aperture. 3.

Post-processing: If you don't have a camera or a mobile phone that can manually adjust the focus of the background, you can also use post-processing software, such as Snapseed, VSCO, etc., to blur the background after shooting. In short, if you want to shoot a clear background blur of people**, it is best to use a mobile phone camera with a bokeh background function or a mobile phone that supports manual focus, and pay attention to adjusting the focal length and aperture when shooting, as well as choosing the appropriate shooting angle and distance. Feasting.

Operate your phone: Huawei.

Operating system: HarmonyOS20

The steps to adjust the background of the phone are as follows:

1. Tap to open the phone's camera, and then tap the large aperture icon on the shooting page.

2. Then we turned on the camera's large aperture function.

3. You can set the level of the aperture below, the higher the level, the greater the degree of background blur in the future.

4. Then after setting the aperture, we can see the aperture level number in the lower right corner.

5. Then click on the object to focus on the photo, so that the background of the object is blurred.

6. Remember to close the aperture after shooting.

The advantages of Huawei phones are as follows:

Good battery life. If you have used both Huawei phones and other brands of mobile phones, then you will find that both Huawei and Honor mobile phones have very strong battery life. There are also some personnel at home and abroad who have carried out the mega car test, and Huawei's high-end flagship mobile phones have Lao Wei on the list, and the performance is very outstanding.

The high battery life of Huawei mobile phones comes from the EMUI system's suppression of background programs, which will curb the automatic operation of background apps and save the phone's battery family, which is what netizens often call the phenomenon of killing the background. <>
