Right. I don’t need a 48MP image but a 48MP sensor behind a depth of field image would be pretty useful.
The thing about people taking pictures is they interrupt the flow of a live experience. My ex specifically bought a digital camera with a quiet boot up (low noise focus motor) so she could get shots of our friends before they knew she was taking pictures.
Being able to take the shot and work on focal length later would be less disruptive.
You can pickup the Lytro cameras for cheap on ebay. It is a fun piece of tech to play with. There really should be a microlens array for modern cameras since the pixel counts are so high, and with AI able to do all these crazy convolutions, it could make sense out of even garbage optics.
