More beautiful than imagined: the extreme night self portrait experience of vivo S9 mobile phone



Self portrait has always been the strength of vivo mobile phone. From “soft light self portrait” to “light up your beauty”, these concepts are deeply rooted in the hearts of the people in recent years, and have been favored by many consumers, especially female users. In 2021, the mobile phone fashion products vivo s series for fashionable young groups will launch new products again, new vivo S9 is upgraded to “double soft light polar night selfie” in terms of selfie. It adopts the first polar night micro slit fill light, and its sensitivity is greatly improved. Combined with the new polar night portrait selfie algorithm, selfie will no longer be limited to dark light, even in polar night environment. Today, let’s take a look at the performance of vivo S9 in the self portrait at night!

Three kinds of light filling methods can shoot the most beautiful self anywhere

In the past, there were two aspects to decide whether the software was good or not. In the case of sufficient light in the daytime, in fact, most mobile phones now have very good self portrait effect, but the real test of self portrait ability is whether people are satisfied with the photos taken at night when the light is not enough. Many mobile phones take self portrait at night or the faces of people and objects are not bright enough It even looks dirty, or it has a lot of noise and a very fake feeling.

This time, vivo S9 is equipped with the industry-leading isocell slim GH1 + front camera, with 44 million ultra-high pixels, AF autofocus and F / 2.0 aperture, and the first new generation of isocell plus 2G pixel isolation technology improves the sensitivity by 12% compared with the previous generation of sensors, and has better color restoration performance, which lays a solid foundation for obtaining clear and bright night scene self photography. At the same time, this mobile phone also has the “five super texture beauty” of vivo, which starts from the underlying algorithm, and evolves from 2D point-to-point algorithm to 3D modeling algorithm, The beauty effect has been improved qualitatively. But more importantly, vivo S9 is the first to add the polar night micro slit fill light to solve the problem of light in the night scene from the hardware level.

Polar night micro slit fill light can better fill the light on the face

Vivo S9 is the first to create two micro slit fill lights, which directly provide three-dimensional and soft light source for the face through physical light source, further improving the self photographing ability in low light environment. In fact, rear fill light is very common, but the front camera is also equipped with fill light. Vivo S9 is definitely at the forefront, and it gives two fill lights at one time. This innovation is not easy, because the space at the top of the mobile phone screen is very limited, not only the front camera, speaker, and distance sensor, but also the lightweight feature of the mobile phone. It is in such a limited space, vivo S9 also “plug” into the two fill lights, it is not easy, worthy of the “micro slit” this very characteristic naming method.

As can be seen from the above group of contrast photos, the self portrait effect of the mobile phone in normal mode is OK, very clear, the brightness of the overall picture is enough, and the decoration of the character’s face is very natural and beautiful. However, after turning on the tiny slit fill light in the polar night, the effect of self photographing is improved to a higher level, especially the facial light of the characters is brighter, which can also present a transparent texture at night.

When the mobile phone detects that the self timer environment is dark, it will enable the fill light and the soft light ring at the same time

Of course, in addition to the polar night micro slit fill light can help us fill the light when we take selfie, vivo S9 can also choose the “soft light ring” to fill the light. Its principle is very simple, that is, to fill the light on the face with the light of the mobile phone screen by making the mobile phone screen display more white areas. But what’s more intelligent is that when the mobile phone detects that the environment is dark, it uses the front lens to take a self portrait. The mobile phone will enable the fill light and the soft light ring at the same time, so as to achieve the best night scene self portrait effect. Therefore, vivo S9 actually has three light compensation modes to help us take beautiful and natural self photos.

AI polar night selfie can take beautiful selfie no matter how dark it is

If the light is very dark, will the self timer effect of vivo S9 be so good? For such a scene, this time vivo S9 also has a new AI polar night selfie mode. Through the polar night portrait algorithm, after selecting the night scene selfie, the system automatically recognizes and enters the AI polar night mode.

Unlike using fill light or soft light ring to brighten the face, in AI polar night mode, the mobile phone optimizes the photos by using algorithms such as raw domain noise reduction, AI domain noise reduction and exposure repair. AI polar night mode algorithm will further reduce and brighten the face, learn a lot of facial features through AI, and intelligently repair the unclear facial features in the original environment Section, and superimposed beauty algorithm. At the same time, the background synchronization is optimized to solve the problem that the face is bright but the background is too exposed, and restore the background environment in different night scenes.

More powerful beauty and style choice

vivo The “5-layer super texture beauty” carried by S9 can make us get better results when taking selfie. First, we can create a 3D face model by taking photos, so as to obtain the depth data of face and facial features, such as the height information of nose and mouth, which can not be obtained in 2D plane. For this purpose, we can calculate the area of nose shadow and lip color more accurately and finely, and then match it with the facial shadow or lip color of the same 3D material Lip color material. The 3D face modeling algorithm solves the problems of facial shadow and highlight under the limitation of 2D algorithm, and the beauty material does not fit the face, which significantly improves the three-dimensional sense of facial features and the reality of beauty. In addition, 3D face modeling can also add simulated real three-dimensional lighting effect to the face through the new “3D space lighting” technology, so as to further enhance the authenticity of facial features, beauty and other materials.

It’s beautiful to take a selfie

For the beauty of side face self portrait, vivo S9 also supports the function of side face beauty. When manually adjusting the nose shape, mouth shape and chin, it also supports the optimization of skin texture and skin color and 3D beauty. Side face can also achieve the same multi-dimensional beauty effect, no matter which angle of self portrait, it can achieve the most beautiful effect.

In addition, vivo S9 also has rich choices in the style of self photography, which makes our self photography not only beautiful, but also no longer uniform. For example, “green orange” can achieve yellow and blue light effect, while “steam wave” can bring blue and purple light effect. Don’t worry, the added lighting effect is not compatible with the self portrait. The lighting effect under the mobile 3D lighting technology is very realistic, and you can get your favorite light and shadow by adjusting the angle of the light source.

Vivo S9 also added “Rainbow” and “warm sun” 2D light and shadow styles, as well as “starlight” and “soft focus” special effect filters. “Warm sun” light effect uses 2D window light as the main body of the picture, with a light orange tone, which has a sense of leisure at the window in the afternoon; while “starlight” special effect creates a romantic atmosphere with twinkling stars by superimposing glittering starlight special effect and matching with pink atmosphere tone; “soft focus” imitates the aesthetic and hazy romantic texture created by soft focus lens The edge of the object has a soft light overflow feeling, and the hue saturation is low, showing the feeling of retro photos.

In general, this vivo S9 has many advantages in self photographing. With the blessing of excellent performance, it can help us take good-looking self photos in any light conditions and environment. In particular, the first two micro slit fill lights greatly improve the quality of the night scene self photography, no longer afraid of the polar night environment, how to shoot on how to shoot.
