Apple published another new video in its “Shoot with iPhone” series. This one is called “How to shoot with zoom on iPhone 7 Plus.” It offers two methods I don’t know you could use. The first is to single-tap your display for a 2x optical zoom. The second method is to touch and hold your display to scroll through your zoom until you get it where you want it. There are now 20 videos in this series, and they’re great resources for making the most of your iPhone’s camera.
