Who is the king of mobile phone photography: Galaxy Note 8, iPhone 8 Plus photo comparison and evaluation | Ainongji

It can be said that the iPhone 8 Plus did not give us much surprise in terms of pure hardware. The physical parameters basically maintained the level of the iPhone 7 Plus. Even the press conference claimed that the "larger photosensitive area", which was confirmed after the disassembly of the foreign media TechinSights Still 1.22 μ m For Samsung, the main parameters of Galaxy Note 8 maintain the hardware specifications of S8, Sony IMX333/S5K2L2, 1/2.55, 1.4 μ m, F/1.7 However, in terms of hardware parameters, no matter Samsung or Apple, There is no breakthrough in the main hardware specifications of both 。

In terms of secondary camera, the Galaxy Note 8 is the first Samsung flagship mobile phone to use dual camera, and its Both cameras are equipped with optical anti shake , and the aperture of the secondary camera is as high as F/2.4 , which is the same specification as the iPhone X that has not been released yet. Although the iPhone 8 Plus is Apple's second generation dual camera phone, its secondary camera still maintains the specifications of the iPhone 7 Plus last year, Not only is there no optical anti shake, the aperture is still F/2.8 。

Main camera

Note: 7 Plus and 8 Plus are in DCI-P3 mode, which is not supported by most devices, and color deviation will occur. When taking photos for comparison, we have converted the color mode of the photos of the two mobile phones to sRGB.

In this group of daytime proofs, 8 Plus performs well in noise smudging, and the font part has a purposeful sharpening effect.

After zooming in

In the daytime sample, we found that the color saturation and contrast of the 8 Plus sample were significantly improved compared with the other two. The color was very rich, and the algorithm was very sophisticated.

After zooming in

The 7 Plus and 8 Plus still maintain a good daytime white balance, while the S8+has a slightly poor daytime white balance.

In terms of daytime live shooting samples, we choose 7 Plus and Samsung S8+to compare with 8 Plus. There is no significant difference in the analytical power between the three, but the 8 Plus sample is sharper. In terms of noise, the three are also similar in level, and they can win or lose each other in different scenes.

It can be said that the biggest difference between the three machines in the daytime proof is the color and white balance. The tolerance and contrast of the 8 Plus proof are significantly higher than those of the other two. The color is rich and colorful, and the overall proof effect is more beautiful and pleasing to the eye. Moreover, its daytime white balance performance is as stable as that of the 7 Plus, while the S8+is slightly worse.

In this group of proofs, only the font in Note 8 is not affected by the light source, and the word "excellent" is still clearly visible.

In this group of samples, because the sky part belongs to the ultra weak light environment, 7 Plus and 8 Plus have a lot of noise, and the sky part is very dirty, while the sky part of Samsung Note 8 is relatively pure. (Readers can click the picture to view the original picture)

Weak light photography can be said to be the most bottleneck part of mobile phone photography at present. Although Apple officially said that "a sensor with a larger sensitive area was used this time", after TechinSights disassembled the iPhone 8 Plus, although the overall sensor area of the iPhone 8 Plus did increase by 0.5mm ² this time In fact, the unit pixel size is still 1.22 μ m, which is consistent with the previous generation of iPhone 7.

However, the weak light imaging of 8 Plus still did not give us a sense of surprise. It can only be said that it was a small improvement and did not catch up with Samsung. The weak light photography of Samsung flagship (Note 8) can still open the gap with Apple.

This time we selected a scene with ultra weak light and complex light for comparison. In the weak light scene, white balance has become less important, and details retention and noise control are the key to success in this link. In this link, the overall performance of 8 Plus can only be said to be rich in color and pleasing to the eye. Its noise control and detail retention are not much better than that of 7 Plus, which is very mediocre in front of Note 8, while the performance of 7 Plus is the worst of the three.

The performance of Note 8 is very eye-catching. Its sample appearance is very pure. In many scenes, its noise control and detail retention are better than Apple's.

Subphoto

In fact, the sub camera parameters of the iPhone 8 Plus this time are basically the same as those of the previous generation, while the Note 8 is Samsung's first dual camera flagship, but it is equipped with a sub camera with luxurious parameters. Theoretically, the sub camera of the Note 8 should be able to hang the iPhone 8 Plus.

At present, the flagship mobile phones equipped with dual zoom on the market switch to the secondary lens at the long focus end when they have twice the lossless zoom. Because the hardware parameters of the secondary camera are worse than that of the main camera (aperture is too small, and most of them are not equipped with optical anti shake), the effect of using the secondary camera may be worse than that of using the digital zoom twice of the main camera in low light scenes, Therefore, many manufacturers use algorithms to control the switching of double photography, Give Way The long focus side camera of many mobile phones can only be used in sufficient light When taking pictures with weak light, the main camera turns on twice the digital zoom.

In the 10 weak light scenes just taken at night, we all used the 2x lossless zoom of two mobile phones at the same position to take photos. indeed, The auxiliary camera has no optical anti shake, and the 8 Plus and 7 Plus of F/2.8 are completely destroyed in 10 weak light scenes, and the long focus auxiliary camera cannot be turned on , the whole process is double digital zoom with the main camera; In Note 8, due to the strong configuration combination of optical anti shake+F/2.4, 2 out of 10 scenes in Note 8 can successfully start sub photography.

Scene 1: Two details enlarged

Scene 2: Two details are magnified

Due to the optical anti shake+F/2.4, the long focus sub camera of Note 8 has some room to play in the night scene. In addition, after our test, the 8 Plus long focus sub camera often fails to open in the room with light, while the success rate of Note 8 is much higher.

Therefore, in this link, because the secondary cameras of the two iPhones were completely destroyed, Note 8 can be said to be the advantage of the compaction level. The Note 8 demo after the secondary camera was opened has no comparability with Apple's digital zoom demo. The former has a huge advantage in detail retention, and Apple's digital zoom is unable to recover. however......

In the same scene, press the shutter several times. Note 8 on the left uses the double digital zoom of the main camera, and on the right, the long focus sub camera is successfully turned on

In fact, in the two night scenes when Note 8 turns on the telephoto sub camera, it is not 100% successfully turned on Love to play computer games It is found that Note 8 has a certain chance to open in these two scenarios, Because in these two groups of samples, we pressed the multi shutter several times, and only some samples of Note 8 successfully opened the long focus sub camera, while some samples still used the main camera for twice digital zoom.

Through the exif information of the Note 8 sample, we like to find that when the shutter is between 1/20~1/17 and ISO 200, Note 8 will selectively turn on the telephoto sub camera, that is, the environment of these two scenes is just the critical environment for Note 8 to turn on the telephoto sub camera.

summary

The performance of the iPhone 8 Plus in the photo comparison and evaluation did not make us feel bright, while the performance of the Samsung Note 8 was unusual, further opening the gap with the flagship of Apple on the basis of the original lead, especially its high specification telephoto, so that the lossless zoom has more application scenarios. Regrettably, although the iPhone X has not been officially launched yet, since its rear camera is no different from the 8 Plus, you don't need to expect a stronger watch for the main camera of the iPhone X, but the long focus sub camera of the iPhone X is equipped with optical anti shake and F/2.4 big aperture, as is the case with Note 8. I hope that after the official launch of the iPhone X, It can compete with the Samsung Note 8 in terms of sub photography.

At the end of the evaluation, we did an interesting test. The sub camera of Samsung Note 8 cannot record 1080 60FPS video and slow motion video, while the sub camera of 8 Plus can support 4K 60FPS, 1080 120FPS and other high specification video recording. Like its main camera, of course, the premise is that the sub camera of 8 Plus can be successfully opened.
