After the initial novelty of iOS’ “Live Photos” wore off — several years ago — I’ve mostly ignored it. To me, it’s too gimmicky, and because it also records audio, I’m always a little worried that it’s going to leak information if I share the photo with someone else (“…smile for your evil Aunt!”).

But I’ve recently stumbled upon a new use for it that is making me reconsider.

Earlier in the day, I was taking a photo of a waterfall, which Live Photo really is good at, and had left the feature turned on. Later, I had snapped a selfie with a group of friends. When I reviewed the photos later, I was sad to discover that the selfie sucked because one person had their eyes closed. Because Live Photos was still enabled, I was able to pick a new key frame where their eyes were open, rescuing my only snapshot of the evening.
