4 Enable the Camera Grid
Taking great photos with an iPhone is a skill in itself, and you can read more about it here. But one of the most basic things you can do to improve your iPhone photos is to turn on the Camera grid and use to according to the rule of thirds.
While it doesn’t work perfectly for every photo, it’s a good rule of thumb: try to keep the focus of your shot off-center. You can turn on the grid for the native Camera app by going to Settings > Photos & Camera, and toggling Grid on.
