Moving from camera roll to album on iPhone?

Does anybody know if there's an option to move photos from camera roll in to an album so that they arent in the camera roll but only in that album or is it impossible

No if you move it to an album it stays in both the camera roll and album. If you delete it from the camera roll it will delete from the album. Sorry

Click select in top right corner. Select pictures. Then the the bottom of the screen it says "Add to". Select the album
