Why are photos taken by mobile phones upside down and left and right upside down?

The reason why the photos taken by mobile phones are up and down may be caused by personal operating habits.

1. Generally speaking, as a communication tool, mobile phones are used vertically and normally. The receiver is above and the microphone is below. And the camera also takes this direction as the normal direction. If you take such a picture, it won't be upside down.

2. When taking pictures, you often need to take a "widescreen" horizontal version. At this time, facing the camera, the mobile phone should be rotated 90 counterclockwise in your hand. Complete the photo in landscape format. (This is similar to the direction of rotating a mechanical drawing when dimensioning it, and there is a unified standard direction as a horizontal and vertical mark. )

3. Some people don't pay much attention to the rotation direction of the camera when taking pictures, so they can use it at will. Once bad habits are formed, photos and videos will naturally appear upside down and swing from side to side.

4. Some mobile phones have a reverse save switch. If you are not careful, you may encounter it and save it as an inverse diagram. Refer to the attached drawings

Tips for taking photos with mobile phones

1. Pay attention to the changes of things around you and discover beauty.

There is no special setting for mobile phone photography to allow you to accurately adjust parameters such as focal length and aperture. You can have more energy and time to discover beauty. The only regret is that the controllability of mobile phone shooting is very poor. You can only always pay attention to the beauty around you and rely on your own wisdom to "discover" the beautiful things around you.

2. Give up the zoom function

Give up the zoom function of the phone! From a technical point of view, the zoom function of most mobile phone cameras is actually digital zoom (also known as digital zoom), and its principle is simply to zoom in and out on the original image, which may lead to ugly Massek in the image. If it's a close shot, get closer, otherwise go farther.

Shoot in a well-lit place

Now the effect that mobile phone image sensor can achieve is very good, but compared with digital SLR camera, there is still a long way to go. Adequate light is very important. Find good light (natural light or artificial light).

4. Photography angle

It is almost impossible to control the shutter speed and sensitivity of the camera with a mobile phone, but the shooting angle is completely controllable. Most mobile phones will display tic-tac-toe games to help you choose a good angle. You can also learn the following three composition methods.

5. Photographers should not be addicted to taking pictures with their mobile phones.

No matter how good the mobile phone is, it can't be a photographer's dinner man, so don't indulge in it.
