How to set the night mode of iphonexs camera?

In the past two years, after domestic mobile phones, such as Huawei, joined the "Super Night Scene" mode, the night photo effect of the iPhone was completely invisible. However, on the newly released iPhone 1 1 series, Apple finally lived up to expectations, adding a new function of "night mode" to take clear photos even in the absence of light, and finally stopped "blinking".

As the name implies, "night mode" is a camera mode used at night, which is mainly attributed to the new lens and new machine learning algorithm of iPhone, which is unprecedented on iPhone. Although the photo will be brighter in this mode, it will still retain the feeling of night and balance the light and dark elements of the image. In other words, night will not be regarded as day.

How does the night mode work?

The night mode uses the new wide-angle lens of iPhone 1 1 series. It is equipped with a larger sensor, which can let more light in and make the photos brighter in case of insufficient light.

In addition, the night mode uses the new sensor, machine learning algorithm and neural engine in A 13 processor to create night photos.

When the iPhone enters the night mode, the camera will analyze the amount of available light, and then select the appropriate number of frames required for taking a series of photos within a certain period of time, such as one second, three seconds, five seconds, and even longer in some cases. These photos were taken under different exposures, some long and some short, similar to what iPhone did when synthesizing HDR photos, so as to optimize the display of the best part of the scene through synthesis.

When using night mode, you need to keep the camera stable. OIS optical anti-shake function can reduce the jitter of photos. A 13 chip will analyze every shot, throw away blurred images, fuse all the clearest photos, and finally synthesize one. In the meantime, Apple's software algorithms will adjust colors, eliminate noise and enhance details.

Combining multiple photos can make the night mode get more light than a single shot, which is why you can see the photos brighten and get more details.

Because all calculations in night mode are done in the background, you can't choose from a series of photos like continuous shooting mode.

In short, night mode is the result of better camera sensors and Apple's behind-the-scenes "magic".

Activate night mode

The night mode will be automatically turned on when the lighting conditions are poor, without manual turning on. At the same time, click the moon icon at the top of the camera application interface to enter the night mode setting, which can adjust the length of photo shooting in some cases.

Turn off night mode

Click the moon icon slider at the top of the camera interface and slide all the way to the left to turn off this function. However, the night mode is automatically turned on and cannot be permanently disabled in the settings.

Night mode lens

On iPhone 1 1, the night mode is limited to wide-angle cameras, because it is the only camera that supports OIS optical image stabilization, and the night mode requires a camera with 100% pixels to analyze and analyze its images.

On iPhone 1 1 Pro and Pro Max, night mode can be used with wide-angle lens and telephoto lens, and both lenses support OIS optical image stabilization. But it can't be used under a super wide-angle camera.

Time interval for using night mode

Generally speaking, the darker the photo theme, the longer the shooting time in night mode. You can also click the moon icon slider at the top of the camera interface to set it manually. If it is completely dark and the shooting time is too long (for example, 10 second), a tripod is needed.
