I don't think I have specific questions now, but I'm excited for the kinds of interactions it can spark. I mostly imagine getting lost in a sea of QR codes if it is not managed well. I was going to try to composite an extra copy for photographer reference.
If you want reference tier photos for documenting family history, modern mirrorless is better. DSLR from 10-15 years ago is also still great in all but the most challenging light conditions, where you could simply use a flash.
