I created a new album on IPad, how can I remove duplicates?
Duplicate albums? Duplicate photos? Either way, select the one you don't want and delete it.
i am trying to separate photos into album but if I delete it from "All Photos"
it deletes it from everywhere.
Yes, that's true. Albums are just lists of photos, not a separate storage space. A photo may be in zero, one, two, or many user albums, but always in "All Photos" until deleted entirely.
How can I tell it what album to go into when I take a new photo?
Photos only puts newly taken photos in "All Photos" and "Photos" (Moments, Collections, Years). You have to assign them to albums yourself.
