Top vs. iPhone 7/Galaxy Note7/LG G5 Photo Review | Aikiji - 上海419贵族宝贝-上海后花园1314-上海品茶网-阿拉爱上海

Since Galaxy Note4, Samsung has begun to catch up with and surpass iPhone in mobile phone photography, while LG has made great efforts in photography since G4, and has become the first step in smart phone photography. In recent years, the photographic quality of smart phones has greatly improved, which has surprised many people in the industry. Today, we dare not say the general view of card second mobile phones.

Although limited by size, smart phones can't use huge sensors and lenses, they rely on powerful ISP, algorithms, and advanced photosensitive technology to make mobile phones take photos continuously. Although Apple abandoned the 8 megapixel camera in the 6s Plus generation, in fact, we did not see the amazing photo performance on the 6s Plus, which is quite different from the Galaxy Note 5 series in the same period. This time, a new 12 megapixel camera was used on the iPhone 7, and it was the first time that optical anti shake was used on Apple models below 5 inches. Before starting the evaluation, we also saw some samples from foreign media, which made us very curious about the photography of the new generation of iPhone 7.

In this photo review, we selected the previous generation of Apple models iPhone 6s Plus Samsung's strongest camera phone in service Galaxy Note7 Famous for abnormal analytic power LG G5 These three representative smart phones and iPhone 7 Make a comparison (why not compare with the iPhone 7 Plus? Shh~because our shiny black 7 Plus has not arrived yet).

remarks ： The photos taken by the rear camera of iPhone 7 are all in the DCI-P3 color standard and cannot be displayed normally on most display devices. Therefore, in the test, we converted all photos of iPhone 7 into sRGB mode for comparison.

daytime

In the daytime scene, due to sufficient light, none of the four mobile phones will lose a lot of details due to weak light or noise. Generally, the gap between them will not be particularly large. However, we noticed that in the daytime sample, the overall picture color of the LG G5 would be a little distorted, and its white balance performance was not as normal as that of the other three machines.

In this group of samples, iPhone 7 has a rich reserve of tree texture details, obviously superior to iPhone 6s Plus, Galaxy Note7, and the most accurate color restoration.

In the comparison of these two groups of enlarged proofs, Galaxy Note7's font resolution is obviously inferior to that of iPhone 7, and even worse than that of LG G5.

Daytime summary : It is also a 4:3 frame scale of 12 million pixels. After zooming in the details of the sample, I can see that the analytical power of Galaxy Note7 is not as good as that of iPhone 7, which may be related to the fact that Galaxy Note7 uses a larger wide-angle focal length of 26mm (iPhone 7 is 28mm), or it may be affected by the special smear algorithm of Galaxy Note7 (mentioned below), But it is clear that LG G5 has a strong analytical power. This advantage is not only brought by its additional 4 million pixels, because its analytical power at night is much stronger than that of a mobile phone (mentioned below).

In the daytime scenario, Note 7 has less details and low image sharpness, while LG G5 has the richest details. The iPhone 7 is second only to the LG G5, and its white balance performance is the most stable and accurate of the four mobile phones.

at night

In most night scenes, the imaging style of iPhone 7 is similar to that of iPhone 6s Plus. It is difficult to distinguish who is 6s Plus and who is iPhone 7 without zooming out to see the details. However, if you zoom in carefully, you will find that iPhone 7 will deliberately increase the exposure of dark parts to increase the details of the painting surface, and at the same time, it will smear the dark noise, especially in the ultra weak light environment, This change is more obvious.

In this group of ultra weak light samples, the analytical power, purity and image exposure of Galaxy Note7 are significantly better than those of iPhone 7

In this set of weak light proof sheets, the font details of Galaxy Note7 are lost, and the analytical power of LG G5 is simply stronger than that of the other three mobile phones.

Compared with the iPhone 6s Plus, the iPhone 7 has a great improvement in dim light and ultra weak light, but it is slightly inferior to the Galaxy Note7. Note7 is better than the Galaxy Note7 because of its high picture purity and low noise. Its dark noise is smeared in a large area, and the picture exposure is a small gear higher, but it may be due to the active smearing algorithm of Note7, This causes it to smear some details in some scenes.

Summary of night photography : Due to poor night light, it is easy to generate a large number of noise points under ultra weak light, which is a great test of the mobile phone's photography algorithm. Excellent algorithms can reduce noise points and improve the purity of the image by smearing, which is very simple and crude for the overall appearance of night imaging. If the algorithm is good enough, it can also improve the resolution of the image on this basis. LG G5 totally beats the iPhone 7 in terms of exposure, detail, purity and noise. The iPhone 7 only has a slight advantage in white balance in the night scene, and the Galaxy Note7 only has a small advantage in image purity. The imaging improvement of this generation of iPhone 7 is mainly weak light, but the night view The overall performance is still not as good as Note7 and even worse than LG G5. However, compared with the previous generation, the improvement is still worthy of our affirmation.

user's experience

In terms of imaging results alone, LG G5 will undoubtedly win the first place. However, we know that whether it is taking photos with mobile phones or cameras, the experience of taking photos is also a factor that greatly affects user consumption. What is the experience of taking photos? Focusing, view taking, and manipulation can all be regarded as a use experience. Even when the Wi Fi SD card was not available earlier, it was also a very important use experience for the camera to transfer pictures to the mobile phone via Wi Fi.

focusing : For a mobile phone, we carry it with us, and many moments are fleeting. Whether we can capture quickly after focusing will affect the use experience. Among the four mobile phones, the fastest focusing speed is The Galaxy Note7 of the full pixel dual core AF sensor can focus at the moment of shooting, and can not feel the presence of focus. The focus of iPhone 7 is also fast, but if the ultimate contrast is still slower than Galaxy Note7, LG G5 is slightly slower than iPhone 7, and iPhone 6s Plus is the slowest.

Viewfinder : Maybe many people think that shooting is nothing. In fact, when we actually use mobile phones to take photos, we will find that on some high-end smart phones, their shooting is very real-time, and the shooting picture is almost synchronized with the shooting picture. If the shooting is slightly delayed, it will also affect the use experience of photography. Under normal circumstances, when the daytime light is sufficient, even the shooting of the thousand yuan machine will not have a high delay, but the situation is different when the light is weak. Low light condition, The shooting of Galaxy Note7 has the highest synchronization rate with the shooting picture, and there is almost no delay 。 The iPhone has always done a good job in photographing experience. The shooting delay of the iPhone 7/6s Plus in low light is low, and the LG G5 will feel obvious delay, which is a weakness of the LG G5.

Control : In fact, the mobile phone does not have high requirements for photo manipulation, because the mobile phone does not have a dial like the camera, nor does it often use the manual gear. The camera interface of iPhone 7 is basically the same as that of iPhone 6s Plus, which is also the consistent style of iPhone. It does not give users too many options, nor does it have manual mode. Both LG G5 and Galaxy Note7 have strong manual modes, but Galaxy Note7 has more functions than LG G5.

Add: LG G5's shutter response speed (non shutter time) is significantly slower than iPhone 7 and Galaxy Note 7 in some low light scenes.

summary

Many people have misunderstood the photos taken by iPhone, and too many people have mythologized the photos taken by Samsung. We believe that the iPhone 7, Galaxy Note7, and LG G5 are all on the first step of smart phone photography, but they only focus on the three.

Galaxy Note7 has excellent smearing and noise reduction algorithms at night. It can also maintain high purity under ultra weak light. At the same time, it focuses fastest, but it will lose some details. Its samples are colorful and pleasing. Galaxy Note7 is very suitable for photographing portraits and scenes in low light, but it is slightly weaker when strong parsing is required for shooting fonts.

The analytical power of LG G5 can suppress all normal smart phones (except Nokia 808 and Panasonic CM1), and the weak light imaging is also very strong. The analytical power under weak light is second to Galaxy Note7 and iPhone 7, but its purity is slightly lower than Galaxy Note7 The color of the proof occasionally has problems, the white balance performance is not as good as the other two, and the shooting delay will affect the actual shooting experience.

The white balance and color performance of the iPhone 7 are the most stable and accurate both in the daytime and at night. However, since the photos taken by the iPhone 7 are all DCI-P3 standard, there will be some deviations between the colors you see and those seen by others. The resolution power of iPhone 7 during the day and at night is a little stronger than that of Galaxy Note 7. Its weakness lies in the purity and noise control at night. The iPhone 7 with a large aperture and improved algorithm performs significantly better in the night than 6s Plus. Its focusing speed and view speed are only inferior to Galaxy Note 7. Finally, the maximum resolution of photos sent to the circle of friends by iOS WeChat client is 1440 * 1080, while that of Android is 1280 * 960, which is why iPhone photos sent to the circle of friends are clearer.
