Optical zooming is often overused as it is better to walk closer to the subject. But if you cannot, then you should be careful about using the optical zoom because it does increase the chances of blurring. You should use a tripod or find a way to steady the camera on a table, next to a wall, or on the shoulder of a friend if need be. The good news about optical zoom is that the results are superior to digital zoom, so if you need to use it, go with the optical.

Portrait Shots

The iPhone 7 offers a Portrait mode which automatically blurs the background when taking portrait photos. By swiping to the Portrait mode, your iPhone will tell you if you need more light or if you must move back. You’ll need to experiment a bit to find the right balance of light, distance, and framing. It may take you a few photos before getting the look you want, but it will be worth it when you see the results.

Using Third Party Apps


There are several third-party apps that allow you to get the most out of the dual-lens camera, some of which allow you to switch from telephoto to wide-angle and back depending on your needs. However, there are other apps that open the possibilities.
