How Can I Delete Some Shared Photos and Keep the Rest?

[Skeezix]

I recently enabled sharing of photos with my wife. Now I can see all the photos that she took, and she can see mine.
Unfortunately, most of her photos are of stuff of no interest to me, but some of them I want to keep. I can select her photos, but I don't see how I can delete them. How can I delete some of her photos from my phone and keep others without breaking our shared connection?

I don't use the sharing option, but I think the options you have are to share all photos or to share photos that only have certain people in them. You may want to consider ending the sharing and just periodically asking each other to manually share certain photos that you want.
