In the settings of iPhone, find and enter "camera"; In the camera settings, turn on the three items of "super-frame shooting", "super-frame shooting video" and "automatic application adjustment" to turn on super-frame shooting. When taking photos and videos with the Super Photo Frame function, the file formats recorded by the iPhone camera must be set to HEIC and HEVC, but the Super Photo Frame function cannot be used in the picture compatibility mode. In addition, photos taken with the "Super Photo Frame" function will have a special logo in the album. If you see the "super frame" sign in the upper right corner of this photo, it means that this photo was taken with a "super frame". After shooting, you can correct the horizontal direction of the photo by editing the secondary composition in the photo album and adjusting the horizontal line of the photo.
