How do you remove an image from an album without deleting it?

In my opinion, you created the album so deleting an image is not easy because all the images that meet the criteria are included. To delete a picture, you need to delete it from the library.

 As I understand it (and when image indexing is working properly):

Save an image directly to an album.
Save same image to second album.

Delete from second album - image remains in 1st album
Delete from 1st album - image is gone from saved images.

I save all my images to the default ALL IMAGES location.
Adding images to one or more appropriate albums.
Removing from specific albums images I want to keep available and if I want to remove the image from my image collections, I remove it from the ALL IMAGES location.

I believe this is what works all the time.
