d9780 If my google photos app is open can it somehow access my graphene camera photos?
It depends on the permissions you've granted to Google Photos. If you don't want Google Photos to have access to all of your photos, you can use Storage Scopes. If you don't want Google Photos to have access to all photos, make sure the "photos and videos" permission is denied.
Don't know if Google Drive does that automatically or not. If it does, you'd want to review Google Drive's permissions as well.
