Searching for all unnamed people in Photos 3.0 and 4.0

The new workflow to name faces in Photos 3.0 and 4.0:

The Face detection in Photos changed considerably between Photos 2.0 on Sierra and Photos 3.0 on High Sierra. Previously, in Photos 1.0 and 2.0, we had an album with all unnamed faces, where we could reject and remove the faces of people we are not interested in, weed out the statues, false positives, or strangers in the background, and keep only the faces we want to name.

Photos 3.0 on High Sierra introduced two significant changes, that make it necessary to change the workflow drastically:

• We can no longer reject automatically detected faces at all. The faces circles around the faces of strangers in a crowd with and "unnamed" below it will clutter up the photos and cannot be removed. Photos seems to need to know about each and every face in a photo to be able to classify the photos into categories.
• There is no longer a strip or album of unnamed faces at all. We have to find a different way to check, if we have tagged all faces that we want to name. It makes perfect sense, that the album of unnamed faces has been removed, as we can no longer weed out the irrelevant faces to make such an album manageable. It would be like searching for a needle in a haystack to find the unnamed faces that we want to name among the thousands of faces of strangers in the background or statues or paintings.
• Now, Photos will instead present us with a few albums of unnamed faces, only for the people it recognized in at least fifteen photos as the same person to get started.

The new workflow to name more photos is to open these existing albums and to use the "Confirm additional faces" option. And if we want to add more people to the People album, we name a few faces of this person by starting from a photo of this person. To see unnamed faces while browsing photos enlarged, we have to enable "View > Show faces name". With this option on, Photos will draw a circle around each detected face.Just type a name below the circle, if you happen to come a cross a person you want to add to the People album. I would start by looking at photos from an event like a meeting or family party, where we met some of the people that we want to name.

To recreate an album of unnamed Faces:

To recreate an album of unnamed Faces create a smart album with the rule Person is not %(https://apple.stackexchange.com/questions/287148/photos-smart-album-for-photos-w ith-no-people-at-all)It will show any photo with no named person in it.

But it will include all photos with no face at all. It is just looking for photos without named people. We have to do some extra work to weed out the photos with no people at all. We have to do this only once by tagging these photos with keywords.I am using two additional keywords. When I come across photos without people in them (nature photos or buildings) I add the keyword "No_People". And if there are unknown persons, I add a keyword "Strangers".

My smart album looks like this:

This way I have to deal with the nature photos without people and the strangers only once. After tagging them, they will no longer bother me.
