How does Huawei p20pro take good photos?

The first is the large aperture mode. Aperture is a device that the lens of a mobile phone controls the amount of light entering the photosensitive element of the fuselage, which can be regarded as a small hole through which light passes. Huawei P20 Pro is equipped with a large aperture of f 1.8+f 1.6+f2.4, and it seems that the larger the aperture, the better.

Night scene mode

Then the night scene mode. Night scene mode allows us to shoot night scenes at night, with pure pictures and less noise. First, shoot the night scene with your mobile phone. The weather must be fine. This is the first element. Secondly, if it is an ordinary mobile phone, we all need a tripod to fix it. The shooting process of night scene mode is about 3 to 10 seconds. But Huawei P20 series need not bother. You can shoot the super night scene directly by hand.

portrait mode

Portrait mode is the best mode to shoot people. It can also highlight the details of the characters and achieve the effect of blurring the background. It can make the focus subject of mobile phone shooting more prominent and bring more amazing photo effects.

On March 27th, Huawei P20 series mobile phones were released in Paris, and landed in the domestic market on April 12. As we all know, P20 and P20 Pro have extremely powerful camera functions, and the authoritative evaluation of DxOMark gives scores exceeding 100, especially P20 Pro exceeds the last champion 10.

So, what did P20 series break through? This paper expounds the revolution brought by P20 series in detail from two aspects: hardware and algorithm.

First, the most advanced photography system.

1, an unprecedented 40 megapixel Leica three lens.

Compared with contemporary mobile phone products, Huawei P20 Pro's most shining feature is its unprecedented rear three-camera module.

In recent years, Huawei has conducted in-depth cooperation with imaging giant Leica and launched a series of smart phones equipped with Leica dual cameras. Now, together again, P20 Pro is equipped with three lenses of VARIO-SUMMILUX Leica:

One is an exclusive customized 40-megapixel color module,11.7 inch super-large photosensitive element, which is matched with an f/ 1.8 aperture lens with an equivalent focal length of about 27mm to restore details and real color information.

Second, the 20-megapixel ultra-clear black-and-white module, with an f/ 1.6 aperture lens with an equivalent focal length of about 27mm, brings classic and rich Leica tones.

The third is the industry's first 8 megapixel telephoto module. With the f/2.4 aperture lens with an equivalent focal length of about 8 1mm, we can achieve about 3 times optical zoom, 5 times triple zoom and 10 times digital zoom.

P20 Pro has the largest CMOS image sensor in the mainstream mobile phone market, which is 2.25 times that of Samsung Galaxy S9+ and 2.7 times that of iPhone X. ..

The larger photosensitive area brings a more compact image effect visually, as well as a background blur effect that is rare in the field of mobile phones.

With the increase of the size of photosensitive element, the size of unit pixel increases accordingly, which means that the light receiving area increases, the exposure increases and the signal-to-noise ratio increases.

The pixel size of P20 sensor is 1.55μm, which is ahead of 1.4μm of Samsung Galaxy S9+ and 1.22μm of iPhone X, and the pixel area is increased.

P20 Pro has advanced pixel fusion technology, which can oversample the information of 40 million pixels into a picture of 654.38+00 Wan Chao pixels. At this time, the size of the unit pixel is equivalent to 2μm, which can achieve a larger dynamic range and higher sensitivity.

The sensitivity of Huawei P20 Pro can reach ISO 102400 in extremely low illumination environment, which is unique not only in the field of mobile phones but also in the field of digital cameras.
