It helps to consider the smartphone as an "input device" rather than as storage and presentation device. You know you've got a real winner of a photo if right away you want to share it with someone. A backlit cluster of leaves on a beautiful fall day - off to my sister who is a master of such shots. A really great photo of the kids - off to a particular Whatsapp group (Facebook has long ago faded for this sort of thing - yes, I know, Whatsapp is still Facebook). And so on.<p>But at the end of the day, or the week anyway, download all the new stuff to my old-school computer and cull ruthlessly. Only the parts that survive that go into the real collection. Which is still a lot, but cross-referenced by date taken <i>and</i> subject matter, the fulfill the "digital diary" role, not the "art gallery" role.<p>Immediate culling is important. Once the photos are a month or two old, for one thing they seem too important to cull any more; for another so many have accumulated that you'll never catch up anyway.<p>My ultimate storage system - homemade and not publishable quality - has a web accessible, rudimentary full screen, swipeable presentation layer, so I can still show off the photos from it in a similar way to showing off photos actually stored on the phone. But it has the culled collection that is merged together from two phones, several old school digital cameras, and even motion capture surveillance cameras watching the front and back yards.
