Let me introduce it to you. It's a full-screen mobile phone, and it's great to take pictures.

IT 168 evaluation just ended in the 11th holiday, the author was once again lucky enough to be the first batch of users of vivo's new mobile phone, and came to Japan with the full-screen mobile phone X20 just released by vivo on September 2nd1for more than ten days of in-depth trial. Cut the crap and share the experience of these days directly with everyone.

Appearance and configuration

In terms of appearance, the front of the vivo X20 is almost entirely a screen, and the front camera, earpiece and self-timer fill light are respectively above the screen from left to right; The edge of the screen glass adopts 2.5D technology, and with the upper and lower black panels, the overall look and feel of the front of the mobile phone is very good.

The back of the mobile phone is designed with a certain curvature and a frosted shell, which feels very fit; The back part adopts a classic layout, with a dual camera and flash in the upper left corner and a fingerprint module and vivo logo in the middle. The whole body design is round, and the camera, fingerprint module, logo workmanship and polishing process are excellent, just like the carefully designed handicrafts on the desktop.

A major feature of vivo X20 is the full-screen immersive experience, equipped with a 6.0 1 inch Super AMOLED full-screen with a screen ratio of 18:9, accounting for 85.3% of the screen. Satisfactory, X20 is also very elegant in screen border technology, with the top and bottom margins of 7.7mm and 8. 1mm respectively, and the left and right margins of only 1.8mm, which makes the whole front of the fuselage look natural and will not affect the appearance because of black edges.

In terms of configuration, Snapdragon 660 equipped with X20 is the mainstream mid-to-high-end CPU, which is well-known for its performance and power control. The trial model is a light and luxurious combination of 4g storage and +64G memory, which can ensure the fluency of daily use and sufficient storage space.

Camera function is another main feature of X20, so vivo is also full of conscience in camera configuration. Vivo adopts the solution of front and rear dual-camera shooting on X20, equipped with dual12 million pixel "all-pixel dual-core focusing" sensor, with unit pixel area of 1.28μm and the fastest focusing speed of 0.03 second. Combined with the new image Rubik's Cube technology of vivo, vivo X20 can still shoot rich dark details and accurate high-light exposure in unfavorable environments such as dark light, low light and large light ratio.

The backlight is also very clear.

From the X9s' "20 million soft light double shots illuminate your beauty" to the X20' s "clear backlight", it can be said that vivo is becoming more and more familiar with the process of solving the pain points of users taking pictures. So, why should vivo emphasize solving the problem of backlight? As a photography enthusiast, the author first paves the way for the cause of backlight pain. Our camera needs to measure light when taking pictures to ensure the accuracy of exposure; Usually, in order to ensure the accuracy of photometry, the camera (in automatic mode) will photometry the focus, and then get a correct exposure value through the algorithm; However, the above mechanism can work normally in a relatively uniform light environment. However, in a backlight (with high contrast ratio) environment, the exposure value obtained by the camera will overexpose the brighter part (dead white) or underexpose the darker part (dead black). This is like the average score of two 100 points and two 20 points is 60 points, but this score can neither represent the highest level in the class nor represent the worst level in the class.

So how does vivo solve this problem? Let's take a look at the following two comparative samples. These two photos were taken through the glass at Shibuya Station. The sunshine was very strong that day, so indoor and outdoor shooting just met the condition of "great contrast of light ratio" Comparing the two pictures, it can be seen that when HDR is turned on, X20' s image Rubik's Cube technology will compensate the exposure of the bright part and the dark part respectively through the algorithm, thus enriching the details of the dark part of the photo (leaves, central black advertising screen, dark glass on the right side, etc.). ), and prevent bright parts (reflection of the sky, central glass, white external walls of distant buildings, etc. ) avoid becoming dead white due to overexposure, which can not only ensure the imaging quality of direct drawing, but also make photos. On the other hand, when HDR is turned off, the shadows of the leaves have darkened. Even if it is brightened later, it is difficult to restore the details, and there are many overexposures in the bright parts. The contrast of the whole picture is too high. It is conceivable that if the light ratio is larger, the effect of the photo will be even more terrible.

The following are some samples of the "backlight HDR" effect taken by the author with X20 in Japan, some of which are a little late with snapseed, so I'd like to share them with you. The level is limited, so clap yo ~

Hand-held night shot

Another pain point of taking photos with mobile phones every day is taking photos by hand at night, which can be regarded as an extension of the "clear backlight" scene, because the night environment itself is dark, and the artificial lighting landscape in the city decorates the night, but it also belongs to the shooting environment with "big contrast of light ratio". So what is the performance of vivo X20? Let's have a look at the samples.

Macro shooting

After watching the shooting of the big scene, let's take a look at the image quality performance of X20 in macro shooting. Macro shooting is a great test of imaging quality, and it has certain requirements for camera metering, white balance, focusing, color adjustment and lens quality. So what is the performance of vivo?

The above two pictures were taken in the KITTE Building next to Tokyo Station. When I came to visit, I happened to meet the "Hong Kong Castle Culture Exhibition". There are many castle models on the first floor. The author took a few pictures casually and sent the above two pictures to a circle of friends. Many friends asked curiously: Why did you just go to Hong Kong to sweep the streets? It can be seen that the imaging ability of vivo X20 is really powerful, and the models shot from macro can be confused with real objects, which is comparable to the effect of street shooting and drone shooting.

Beauty is the last word.

Having said that, I believe you have a better understanding of X20' s camera ability. But what I'm going to say next is actually the real point ~ I believe that most male users have an experience, that is, going out to play with their sisters. When taking pictures of my sister, it is difficult to meet the requirements of my sister, whether because of poor technology or because the environment on the spot is not ideal, which greatly reduces the goodwill.

In fact, in daily life, one of the most important tasks of mobile phone photography is to make people look good, and vivo X20 can just solve the pain points of users in portrait shooting. X20 camera comes with beauty shooting mode, which can adjust peeling, skin color and whitening when shooting, making people look more beautiful like photos. At the same time, photo albums can further beautify photos. Whether it is silly one-click beauty or relatively fine monotony, X20' s beauty function can be said to be very powerful. The following is a soap film taken by my girlfriend on this trip, which is used to press the bottom of the box. I would like to share it with you here, and thank vivo X20 for making me finish the most difficult portrait shooting ~: P

Vivo photo album built-in image editor

X20 photo album comes with simple photo editing tools, but the sparrow is small and complete, and it needs high efficiency. Users can directly adjust the picture parameters such as brightness, color temperature and contrast in the album, and the blur effect can also be adjusted later; If it is too much trouble to adjust the parameters yourself, vivo photo album also provides a variety of styles of filters for everyone to choose from, and directly applying the filters can easily make the photos more stylish.

Compared with the later effects below, the author takes the Leimen shot by Asakusa Cultural Center as a sample, simply sets the filter, adds a dark corner, and then blurs it a little, so the photo style is much more Japanese in an instant.

▲ stylization

The following is a stylized sample of post-processing of vivo photo album. The post-processing idea is similar to the above example. I'd like to share it with you. In fact, later retouching is not complicated ~

abstract

After more than ten days' trial, the vivo X20 is very satisfactory in terms of workmanship, configuration, full-screen experience, surprising photo-taking ability and even the forward-looking function of "face recognition". It is indeed a full-screen mobile phone that can be bought on the market at present and takes excellent photos. Especially for the camera function, I am usually a photographer, and I have two single-lens reflex cameras and 1 micro-single camera. I also brought a relatively portable Quan Huafu micro-bill on this trip; However, during the ten-day trip, the author was lazy again and again and hardly took out his camera to shoot. As for the reason, I can only say that the X20' s photo performance is really amazing, and some colleagues even said that they would consider entering one in the future. In addition, in order to let users experience the charm of full-screen more comprehensively, Funtouch OS has also done enough homework in many operational details, such as lifting the phone to wake up automatically, sliding up in different areas below the screen to return, home, and opening the control bar. There are many similar intimate functions that I won't list one by one. Of course, no product is perfect. This X20 does not use the current mainstream USB type-C interface, but uses the mirco USB interface, but this problem can also be solved by an adapter.

Generally speaking, through this in-depth use of vivo X20, the author has a further understanding of vivo's attitude and concept of making mobile phones, and also recognized vivo's efforts in making products. At the same time, I am also looking forward to the next model of vivo, hoping that it will continue to bring more surprises to users ~
