> By any objective metric it performs much worse

Which is only important if all you care about is a straight line towards perfection. But imperfections can make a work interesting and spark creativity.

> I can be doing group photos at a festival and review the photos I just took

That’s a feature for you, but for many it’s a bug. Friction matters. You can remove friction or add friction to change your behaviour and thus your outcome.

You seem to derive satisfaction from getting as good a photo as you can get straight away. Perhaps you even delete ones which look “wrong”. But other people prefer to carry on with the moment instead of pausing it to review what they just did. Whatever the photo will be, it will be, they don’t even think about it anymore until it’s time to get the film developed and relive the memories at that point. And because they had to make choices (film is expensive) they pay much more attention to each photo and appreciate it on a different level even if someone had their eyes closed.

There’s no right or wrong here, to each their own.
