Google+ Photos Auto Backup visible from Drive?

[Thanachart Subgranon]

Can I view my photos auto-backup-ed to Google+ Photos from Google Drive? And I believe if I set it to full size backup, the backup-ed photos will take space in my Google Drive, correct?
If true, how can I know how much those photos use my Drive space? Thanks.

No to seeing them in drive. yes to them taking the drive space if full sized.
