Apple’s Stock Camera App has a few great new features in iOS 11, but one of the more interesting ones is a level that helps you take photos of documents and nicely plated food from a top-down perspective. Unfortunately, you’d never know it was there since it’s not enabled by default, and there is no obvious setting for it.
To unlock this new hidden feature on your iPhone in iOS 11, just head to your Settings app, then tap on Camera to view its settings. In previous versions of iOS, the Camera Apps was bundled in with the Photos app’s settings, so it’s nice that they finally separated them.
In the Camera settings, all you have to do is toggle on “Grid.” This will overlay a grid with four lines making 9 equal boxes over the viewfinder in the Camera app, which helps you apply the “rule of thirds” better in your photographs for more balanced compositions.
By enabling the “Grid” feature, you’ll also be enabling the new level, which shows up as a set of thin white and yellow crosshairs that turn into one bold yellow one when your iPhone is perfectly parallel with the ground or ceiling. This works in Photo, Time-Lapse, Portrait, and Square modes, but not in the video or panoramic options.
