You need to know about the distortion of mobile phone photography.

As shown in the picture, when shooting with a wide-angle lens,

The frequent distortion phenomenon indicates that

Because of the wide-angle lens,

The lens of a traditional camera is within the range of a wide-angle lens, while the focal length of a mobile phone lens is between 28 and 33 mm, which means that it belongs to a wide-angle lens, so there is a distortion problem in shooting.

Case 1: Distortion in overhead shooting

The vertical cup is crooked, showing a crooked appearance

Similar to this situation, it is suggested that the farther away it is, the less obvious the distortion is. Moreover, try to keep the objects that are photographed overhead on a horizontal plane, and don't have goblets and other objects with extremely high heights.

case 2: distortion in the case of flat shot and oblique shot.

a flat-shot cup, two cups of the same size, will be too obvious. It is not so obvious to the naked eye, but there will be obvious distortion problems under mobile phone shooting.

near big and far small: the mobile phone lens exaggerates the visual effect of near big and far small

Let's start with the factors that affect the distortion of mobile phone shooting:

1. Distortion is closely related to telephoto lens.

Mobile phone telephoto lens is the same as close-up shooting.

Take Apple 7P as an example. It has a telephoto lens. Under the premise of the same distance, it can zoom in on the object without damaging the image quality, which can reduce the distortion. However, the telephoto lens of 7P does not work when the light is dark. Is the zoom-in shooting actually carried out by digital zoom, or does it damage the image quality?

2. the distance between the lens and the subject

the farther the lens is from the subject, the less obvious the distortion is. The downside is that if you cut the picture twice later, it will easily lose the picture quality.

3. the mobile phone-specific APP

has an artifact, SKRWT, which specializes in treating the lens distortion of mobile phones for one hundred years.

paid APP can correct the distortion of mobile phone, which is convenient for operation and easy to use.

Here comes the point. Look at the long legs that girls need to take pictures.

Based on the principle that the mobile phone can see the near and the far and the small, we can take pictures from a low angle.

for example, when I travel, I ask my friends to help me shoot higher, and then ......

In the future, more mobile phones will be equipped with telephoto lenses, similar to Apple Huawei's dual cameras, and the latest Xiaomi VI has been equipped with dual cameras. The influence of distortion will be less and less.

So, we will wait and see what will happen to mobile photography in the future.
