Regarding live photos, I’ve found the same joy in discovering we had small video clips of certain eras and events. A couple inadvertent live photos we were going through had the voices of now-deceased relatives in them, which was extra special. I also like how motion from live photos are mixed into memory slideshows.
More than a few movie/TV plots involve an innocent person seeing a bad guy doing something bad. This often didn’t end well for the innocent person. I wonder if inadvertent iPhone live photos have begun to figure in an update to this trope?
