I've got too many GB of photos on my iPhone as I've transferred all of them phone to phone since iPhone 4 via iTunes. It's become overkill. - I've moved from iPhoto to Apple Photos in El Cap and just spent a good amount of time organizing stuff for the first time in a long time. - I hooked up my iPhone over lightning cable and brought years of photos over, and I clicked the box to delete the photos it brought over but Apple Photos didn't delete any of the photos on my phone for some reason. I guess I could go in with image capture and delete them, but I'd like it to work more cleanly. What I want is pretty simple in theory: for my iPhone to backup photos to Apple Photos every night over wifi, ideally when iTunes is syncing. Recent Photos: I'd like to set up a smart album that keeps track of photos added over the last 6 months or a year and then have those photos either stay on my phone or be synced to my phone. This way I have all my recent photos without the heft of several years of older photos & videos. WiFi Only: I don't want to use iCloud in this process, or any other remote server. Local network only. I see a way for iTunes to sync photos to the phone, but not from the phone, which is odd. I'm down to use third party apps if I have to, it's worth a couple of bucks if need be. Does anyone know a way to do this?
