I always wonder what people do with these photos. For me photos are utilitarian. I take a photo and immediately send it to my wife or friend, or upload it to my website for an article, or post it on Instagram or whatever, and then I no longer have any use for the photo on my devices. Once a year or so whenever my storage gets full, I just bulk-delete anything older than 6 months and if it hasn't been saved elsewhere for a specific purpose, then it's just gone forever. I don't miss it, because I already did what I wanted with it, so there's no need for me to keep it around.
What do you actually do with half a terabyte of photos?
