How to switch between dual rear cameras on Apple 7p?

The dual rear cameras of Apple 7p cannot be switched manually.

During normal shooting, the Apple 7p cameras cannot operate at the same time. Only one of the cameras operates independently, and it cannot be manually controlled and switched independently. When using 2x zoom, another camera will be operated, which is two separate video heads.

The control of the Apple 7p camera is performed by the system itself, and the user does not need to operate. The dual rear cameras of Apple 7p use synthetic photography to improve the resolution and imaging quality, add a depth-of-field camera, improve imaging quality and focus speed, and improve the quality of photo shooting.

Extended information:

During normal shooting, the Apple 7p cameras cannot operate at the same time. Only one of the cameras can operate independently, and it cannot be manually controlled and switched individually. When using 2x zoom, another camera will be operated, which is two separate video heads.

There are two 12-megapixel cameras on the back, a wide-angle lens and a telephoto lens. The former uses F/1.8 aperture, and the latter uses F/2.8 aperture.

The number of flashes equipped on Iphone7 plus has been increased from two to four. It will adjust according to the ambient color temperature, and the iPhone 7 Plus dual camera also has an anti-shake function.

In dark light, when using Apple's dual camera, Apple will stop using the telephoto lens. There is no optical zoom function, only a digital zoom that can expand 10X. The image of the iPhone 7 Plus at twice the focal length is a clear image that we have never seen on a smartphone before.

The principle of Apple's system is similar to the current digital zoom technology, but because it uses a long focal length lens instead of software to enlarge the image, the image details will not be damaged, and the enlarged image will be sharper and clearer.
