iOS 15: How to Use Visual Lookup in Photos to Identify Landmarks, Plants, and Pets

Must be only in IOS 15 - just tried this is 14.6 and can not find any "i" button.

Are y'all sure? Is there something called "tags" that are different than keywords? The only keywords I see in my photo library are ones that I added manually. I'm looking in Photos on my Mac. iOS 14 Photos doesn't appear to expose keywords. iOS 15 Photos seems like it will expose more of the EXIF data to the user.

Where do I go to see the tags that it adds automatically?

I know Photos has scanned for faces for years now and photos that are geotagged are searchable by location. But I don't think that's what we're talking about.

It doesn't add tags/keywords, it builds it's own internal 'categories' lists to which it adds all appropriate photos, and these are exposed to the user through the search function - so if in Photos you search for 'car' it will return any photos it has put in its 'cars' category, as well as anything you've tagged with 'car'. There's always a few it gets wrong, but it's sometimes very impressive (e.g. I thought it had falsely identified a photo as including a cat, but there was a very small reflection of our family cat in a window). It will also file a photo under multiple categories if appropriate so you can search 'car tree' to just get photos that include both.

The only slight downside is you can't correct it - if it doesn't recognise there's a car in your photo, you can add a keyword, but if it thinks there's a car in your photo but there isn't, you can't tell it so.

Photos has actually supported this general search function for several years now, though the number of categories it recognises has continued to grow.

That is cool, but you have to add the keywords yourself, manually.
