Apple’s iPhone 12 lineup features a number of improvements to the camera systems and one of those is Night mode expanding beyond the standard rear-facing wide lens and landing on the ultra wide lens and the front-facing TrueDepth camera. Let’s take a look at how to take Night mode selfies on iPhone 12.

Night mode selfies is a selling point for the iPhone 12. To get a sense of what this is, follow the headline link, scroll about halfway down the article to the side-by-side-by-side trio of images, showing a Night mode selfie, a no flash selfie, and a selfie with flash. The improvement is obvious.

Great explainer.
