The year 2017 was a year when most of the domestic flagships took photos backwards. Yijia, Meizu and Nubia all joined the dual photography coincidentally, and the optical anti shake of the main photography was canceled. A year later, all the domestic flagship ships have added optical anti shake, and the one plus six released on May 17 is no exception. Let's take a look now. After upgrading to the IMX519 with optical anti shake, one plus six will compete with the previous generation's one plus 5T, iPhone X, Galaxy S9+.
The metaphysical reason for the collective retrogression of domestic flagship photography last year is that Apple installed dual cameras on the iPhone 7 Plus released in September 2016... The direct reason is that the module of the previous year could not accommodate both optical shake proof and dual camera structures at the same time under normal size.
The main camera of one plus six is changed to IMX51916 million pixels with optical anti shake, 1/2.6 inch, 1.22 μ m, in addition to DCAF dual core focusing, The parameters are close to IMX240/S5K2P2 on S6/Note 5 of the current year (In those days, they were regarded as 1.12 microns.) ， But the aperture is larger, reaching F1.7. In the era of 1.4 μ m IMX362/363 running all over the street, and even Meizu 15, an optical shake proof IMX380 (1.5 μ m) product, the 1.22 μ m high pixel solution may not be able to take advantage.
For the sub photography scheme, the 20 megapixel IMX376K is still used, and the dual F1.7 aperture and the conventional focus segment are still used. The difference is that, The sense of existence of the sub camera is very low, After the main camera has optical anti shake, the sub camera is no longer responsible for weak light imaging, but only for depth of field information. Even the 2x zoom can not trigger the sub camera. It is a "luxury" to use the 376K as a depth of field camera.

Investigation items and scales
The assessment items of imaging effect mainly include:
White balance and metering: In many scenes such as sunlight/light/weak light and extremely weak light, whether the white balance (picture color and wind direction) and brightness can be close to the naked eye;
Tolerance: That is, the ability to show the details of the light and dark at the same time. For mobile phones, this is basically equivalent to the HDR effect, including the size of the processing force, whether the processing is natural and harmonious, whether there is ghost after synthesis, white balance deviation and the decline of discrimination;
Discrimination: Roughness can be understood as clarity, and the sharpness, detail and naturalness of the picture must be taken into account at the same time;
The remaining assessment contents include noise control, color saturation (the industry trend is changing from "realistic" to "eye pleasing"), lens quality (including edge degradation control, anti glare, fog control, wide-angle and pillow distortion control, etc.), and many other contents.
For different users, the proportion of different projects is completely different. The Maoist Party, which likes to zoom in and scan, will definitely put discrimination first, and the proportion is very high; The party in the circle of friends attaches great importance to tolerance, white balance, saturation and other items, but the requirement of discrimination is not high. It would be better for everyone to focus on what they care about.
Photo experience
The core of mobile phone photographing is the photographing experience and imaging effect. The main factors that affect the experience are: The smoothness of shooting and the consistency of the film, Whether the viewfinder has problems such as delay/shadow dragging/frame dropping/noise full screen; Speed, Including focusing speed, shutter response and imaging speed; Film rate, The probability of destroying the tablet by shaking hands; Intelligence, Whether the scene with large light difference and weak light can be identified, and HDR and night view mode can be automatically triggered;
One plus six photography experience is not different from one plus 5T, but there is no HQ mode option now, and the film forming speed is not as fast as that of the previous generation (because multi frame synthesis is enabled by default?). After all, it is dual core focusing. Although the low light focusing speed is not as fast as the full pixel dual core focusing model, it is also faster than the iPhone. It is completely OK. However, the focusing success rate of extremely weak light is close to that of the weaker IMX362/363 model, and there is still a small chance that it will be false.

The virtualization effect is slightly improved than that of the previous generation, and it is enough to deal with the circle of friends. But if you really want to compete, there is a certain gap between the one plus six matting and the blurry discrimination of near and far scenes and Apple Samsung. In addition, because the main and secondary cameras are both conventional focus segments, the virtualization mode itself suffers more (when the situation is consistent, the longer the focus segment, the better the physical virtualization effect itself).
The sub camera with higher pixels does not participate in the zoom. One plus six is equal to using the digital zoom and the optical zoom of Phone X and S9+. The gap is so big that there is no comparability (iPhone X is less than twice the full size, about 1.86 times).
The sample is scaled to one size, and one plus 6 and S9+images can accommodate more scenes (pay attention to horizontal buildings)

How big is the difference of optical anti shake? The lighting of this indoor scene is not bad. In addition to one plus 5T to adjust the ISO to 300, the other three sets maintain their minimum ISO. S9+even judges that the light is too good and uses the aperture of F2.4

Summary
In imaging, the first change of one plus six is Wider angle It has changed from an equivalent 27-28mm to an equivalent 25mm, which is larger than S9+(the equivalent focal length information in one plus 5T EXIF information is incorrect, and the actual imaging field of vision is close to iPhone X). The advantage is that the field of view is larger, but the disadvantage is that the number of pixels that can be assigned to a unit scene decreases. When other conditions are constant, the power of discrimination will be reduced accordingly. As compensation, one plus six increases the sharpening strength. The good news is, One plus six's daytime discrimination has not changed much, but the bad news is that their discrimination cannot be separated from the top flagship of 12 million pixels
And one plus six The gap with the top flagship is mainly due to the dimming of metering and the tolerance of HDR/multi frame synthesis. In daylight, the difference is not big, but in some light and weak light scenes, the picture is dark, resulting in the loss of a large number of dark picture information, and multi frame synthesis fails to pull back the dark.
With larger pixel size and optical anti shake, one plus 6 In the light scene with poor light, the improvement can be seen immediately. The low light scene is like rubbing the previous "four in one" sub camera on the ground The noise reduction and detail performance are also good. Just facing iPhone X S9+， There is still room for improvement. The white balance of one plus six becomes warmer and yellower, and the base color is slightly red. The white balance accuracy is not improved compared with the previous generation. The overall metering is slightly dark, and the extremely weak light is still under exposed.
Overall, This year's one plus six photos have been greatly improved , but we haven't been able to shake the position of S9+and iPhone X for the time being (too high expectations, too strong competitors). And its ranking in the domestic flagship will not be confirmed until we compare it with Xiaomi MIX 2S, Meizu 15 and Hammer Nut R1. Please wait.
But when you think about it, it is not realistic for Apple Samsung to require a 3000 level domestic flagship to start at 6000 or 7000. But every year, there are always some domestic flagship counterattacks vivo XPlay6、 Meizu PRO 6 Plus and the current Huawei P20 Pro have really raised our expectations.
