Facial recognition filtering
So I've never been good at keywording. If my wife and I would travel, I would lazily tag the whole album with both of our names. Many of those photos didn't have her in them. So now I'm starting with facial recognition, and I assumed the keyword filters would work with only the photos where I have confirmed her face through people mode. But it shows everything tagged with her name. Is there a way to get around this?
Also I'm wondering about multiple filters. Lets say I confirm faces on 1000 photos with different combinations of her, my wife, and my daughter. Then I would like to see photos that only have ALL THREE of us. Not all of the photos with any of us in them. How would I do this?
Thanks
