What? I would never trust my photos to automatically go to some cloud storage. Who knows who would have access to them?
Instead I download the photos from all the family phones on a regular basis. I copy them to an external drive in my house. Then they backed up to a cloud service, but they are encrypted before they are backed up and the cloud service is only a backup. We can't actually see the photos on that cloud service. It is just fire protection (and yes, I have pulled the photos and videos back down from the cloud service to make sure it is backing them up correctly).
Can take photos with the Nikon and beam them to my phone fairly quickly. Is it as quick and seamless as using the iPhone directly? Nope. But good enough that I'm ok with it now. It also gives me access to typically a much higher quality photo that I can crop way farther than I can with the iPhone.
