Hello, I have some questions about using Photos. Since I have 3000 photos, I try to move them into different folders rather than displaying them all in one folder. I have the photos on my iPhone (copied?) to Photos. I pressed the plus sign to create album. Then, I went to All Photos to select a long list of photos to album. After that, I went back to All Photos and the photos I just mentioned are still there. Did Photos copy the selected ones to my new album or it moved those photos to the album but still display in All Photos? If I delete the photos in Photos on my Mac, will I automatically delete the ones on my Phone and vice versa?
