Is there any software or method for iPhone 7 to take photos in portrait mode like iPhone 7 plus?

iPhone7 comes with portrait mode, and the system needs to be upgraded to iOS10.1.

Turn on portrait mode on iPhone7:

1. To experience the "portrait camera", you must first upgrade to iOS10.1. Then open "Camera" and swipe left to select "Portrait" mode.

2. After turning on the portrait mode, the top toolbar will be reduced from five to one, and only the delayed shutter function will be retained, which is still very useful when setting up a portable tripod to take photos with friends. , the shallow depth of field effect can also be turned on normally at this time. Of course, it would be better if Apple could add a set of filters to it in the future, such as small fresh ones, and even save the step of retouching pictures.

3. The picture above shows the top toolbar in normal "Photo" mode, and the bottom is the toolbar in "Portrait" mode.

4. It was found that as long as the "Portrait Camera" is turned on, the iPhone7 Plus will automatically switch to the 56mm telephoto camera for imaging. In the viewfinder, the subject is suddenly zoomed in much closer. After comparison I found that this is exactly the same as the effect of manually clicking to switch to 2X zoom.
