Let me count down the flashy photography functions on mobile phones. I’ll do it first. You can do whatever you want.

Many mobile phones now have ultra-telephoto lenses with tens or even 100 times, and some brands also use the ability to take clear pictures of the moon as a selling point. But to be honest, the optical zoom factor of most mobile phones is 2-5 times. As for the effects of other focal lengths, they are the result of cropping + algorithm on the original image.

To be honest, shooting the moon is a bit unreliable. Some mobile phones have built-in moon models of various shapes in advance, and then put the corresponding models on according to the moon photographed by the user. Finally, you can Got a relatively clear picture of the moon.

In fact, the most commonly used telephoto lens in mobile phone photography is 2-3 times, and occasionally 5 times is used, and the most is 10 times. As for 30x, 50x, and 100x, they are all digital zooms, which have no practical value and are more of just a marketing gimmick.

In many people’s minds, it seems that the higher the pixels of the lens, the better the quality of the photos or videos taken, but this is really not the case. Many mobile phones now support 50 million, 64 million or even 100 million pixels, but the photos taken in most modes of the mobile phone default to 12 million pixels, and some even only have 10 million pixels.

Only when you specifically turn on the high-pixel mode can you take high-pixel photos. In high-pixel mode, the phone does not support zoom, and is not compatible with large aperture, night scene, portrait and other related shooting modes. Why is this so?

Huawei has always emphasized the concept of "computational photography" at the P50 conference. This is not a new thing, and is used in almost all mobile phones. In fact, it is a comprehensive technology that uses software algorithms combined with sensors and modern optical technologies to create new photography equipment and related applications. It breaks through various problems that are difficult to solve with traditional digital photography technology and becomes another new revolution in photography technology.

Many functions on mobile phones are the result of "computation", but ultra-high-pixel photos are far beyond the calculation range of mobile phones. Therefore, the high-pixel mode is not compatible with other shooting functions in the mobile phone.

Just like Canon's flagship SLR camera 1DX3, it only has 20.1 million pixels because it has to maintain a continuous shooting speed of 20 frames/second. If the pixels are increased to 50 million, the continuous shooting speed will inevitably be reduced, also because of insufficient computing power. In addition, 20.1 million pixels can ensure a large enough area for a single pixel, thus improving the high-sensitivity performance of the camera.

For a smartphone, the quality of the imaging effect is not only determined by the number of lens pixels, but also by the lens resolution, cmos area size, processor and algorithm, etc., which are all very important factors. .

In my opinion, the curved screen is really useless, and I don’t like it anyway. Whether you are taking pictures or retouching pictures, it is easy to accidentally touch the edges. Moreover, the edges of mobile phones are the most likely to be bumped. The probability of screen damage is much greater than that of straight screens. Even applying a mobile phone film is laborious. From a practical point of view, direct screen has more advantages.

Apple mobile phones all have direct screens, including many international big-name mobile phones. Oh, sorry, there is also a Samsung. Samsung is the pioneer of curved screens, but the problem is that Samsung is now becoming more and more straight on its own mobile phones.

Dolby Vision is an image quality technology launched by Dolby Laboratories in the United States. It improves image effects by increasing brightness and expanding dynamic range. It improves video signal fidelity so images appear lifelike in terms of brightness, color and contrast.

Indeed, the video effects I shot with my iPhone 12pro max are really good-looking, and all processes from shooting, playback, and editing comply with Dolby Vision standards. The problem is that with such a good effect, I can only take pictures and see for myself.

Because most of the platforms and devices around us do not support Dolby Vision, if I share this video to Xigua Video or a video account, others will not be able to see the effect, or even the viewing effect. Not as good as normal mode.

Perhaps playback platforms and equipment will be popular in the future, but the current Dolby Vision effect is of little significance.

Among all the mobile phones I have used so far, OPPO Find X3 has the best screen display effect. Find X3 is the first Android phone to have a full-link 10bit mobile phone.

It can be implemented in "shooting, encoding, storage, decoding, and display". Each step is 10 bits and each step is 1 billion colors!

However, the photos you take with OPPO Find X3 look beautiful on your mobile phone screen, but it may not be possible if you share them because not all devices support 1 billion colors.

This is similar to the Dolby Vision of iPhone 12. Apple believes that Dolby Vision is the future direction of development, and OPPO believes that 1 billion colors is a future direction. As a manufacturer, it is right to have such a forward-looking attitude, and once their predictions are accurate, they can accumulate some technology and experience in advance. But for users, the current practicality is not high.

There are also old masters in mobile photography, such as those who teach you to use professional mode to shoot night scenes

Let’s see how many mistakes you make among the 4 most common mistakes made by novice photographers?

It is said that photography is the art of subtraction. The key is how to subtract. Here are 5 key points for you to follow.

By doing these 7 points, you can also shoot super high-definition paintings. High-quality mobile phone photos
