Why is it on the photo app is that when you add your photos to new albums and when you are deleting from camera roll it will delete photos from everywhere so therefore once your photos are in the albums you have chosen you cannot delete f

Your photos are actually all in the Camera Roll. The album you create only contain pointers to these pictures. Albums are like music playlists; when you delete a song from the playlist it doesn't delete the song from your music library. But when you delete a song from your music library it will also be deleted from any playlists that it may have been in as well.

If you want organize your Photo with albums without have the same photo on camera roll the only way is to make it from pc or mac and then sync them on your iPhone.
