I think there is a difference between not actually looking at the event/object because you want to make photos (or make a perfect photo), vs just ensuring that essential stuff you see got at least a photo.

Nowadays I make a conscious effort, if I am going for some trip/event, to always make at least one photo, so I can remember it. And by now I have photos arranged in a timeline spanning > 20 years, and it is extremely enjoyable to browse it all to remember.
