Why are the photos before and after the mobile phone different? With the rapid development of smart phones, people will prefer to take photos with their mobile phones to record all the beautiful things. Many people want to know why the photos before and after the mobile phone are different. This article will explain why the photos before and after the mobile phone are different.

Why is the front camera and the rear camera of a mobile phone different? 1 Whether we use a beauty camera or a mobile phone built-in camera, the front camera has a built-in beautification function, while the rear camera usually does not. The rear camera is higher in definition, which magnifies the defects of the face.

In addition, when taking selfies, you will be most familiar with which angle suits you best, while other angles are not. So the photos taken by others are definitely not as good as their own.

In addition, the lens just mentioned is also a reason. Although mobile phone cameras are all wide-angle lenses, it will be better to lose weight when the lens is close to the lens when taking a selfie. When someone else takes pictures, you are far away from the camera. No matter how the wide-angle lens is used, the effect is not very good.

Why are the photos before and after the mobile phone different?

1. The focal length of the front and rear lens (the camera you refer to) is different, and the distance between the person and the lens is also different. The people seen in the picture are also different in size. If it is too close, a part of people will be obviously distorted.

2. Because the lens is inconsistent, the shooting quality will be different. Generally, the quality of the rear mirror is better than that of the front mirror.

3. The pixels of the original imaging (COMS or CCD) used before and after shooting are different, so the picture quality after shooting will be obviously different. Usually, the rear camera is much better than the front camera.

How to take a selfie will look better?

First, it is best to avoid direct sunlight outside. If there is really no way to avoid the light, just follow the light when taking pictures. Of course, when shooting a specific scene, you can shoot against the light, or you can shoot a good feeling against the light.

Second, 45-degree selfie is a common way for many people. The photos will be pointed chin and big eyes, which are suitable for both men and women.

Third, the side shot, which face looks good, (generally it will be better to shoot with the left face). Looking up can show your graceful jaw curve.

Fifth, shoot from top to bottom. When the face is low, the face will look thinner.

Why are the photos before and after the mobile phone different? Because their pixels are different, they use different apertures. Pixel is the main parameter of camera. The resolution (pixels) is mainly determined by the image sensor. The higher the resolution, the finer the image and the better the effect, but the image takes up more storage space. Generally speaking, camera pixels are the largest pixels in camera mode, and pixels in photography (video shooting) are usually smaller.

The rear camera of mobile phone is superior to the front camera in all aspects. Except for some models that mainly take selfies, the pixels of the front camera of a general mobile phone are lower than those of the rear camera.

The resolution of mobile phone camera often uses the special terms of image resolution (such as CIF, VGA, etc. ) to represent the resolution (pixel = resolution multiplied by the length, width and sum, such as: 640X480=307200, that is, 30W pixels).

How to view mobile phone pixels:

1, set the photo quality and size to the highest in the camera settings of the mobile phone, and take photos. Then look at the resolution of the photo. If the resolution is 640*480, your mobile phone pixel is 30w. If it is 2560* 1920, it is 500w pixels, and so on.

1, click on the phone settings, and then click on the phone, which will introduce the memory, rear camera, front camera and other contents in detail, and you will know directly.

3. There is another way. Take out the previously assembled mobile phone box and check the detailed introduction in the manual. It says that the mobile phone is equipped with equipment or something. It's not hard to find out how many pixels your phone's camera has.
