I would pay good money for a digital camera that could take photos as well as the average flagship phone and fit as easily in a pocket (and I'm a woman, so I'm including sometimes pathetic little pockets), but they could only be tweaked and edited later, on a computer or companion device.
I think that desire for spaces occupied only by the people in them, not the whole rest of the world and its opinions, explains even more of this trend than the aesthetic of the photos.
