Forgive the obvious questions, I'm new to mac and iPhoto.
I have imported all my photos and I'm in the process of naming faces etc. The most time consuming part i have found is deleting all the randoms in the background and adding in missed faces.
I'm now at a point where quite a lot of pictures haven't had the faces correct identified, if i select 'detect missing faces' does this ignore all the faces I've previously deleted or will it pick them up again meaning i have to re-delete them.
Don't want to just click and see what happens as there will be 1000's of faces potentially adding back in that I've previously ignored.
