Who Are The Faces In The Opening Credits Of ‘Orange Is The New Black’ [VIDEO]

I love this show, absolutely love it.  I'm talking about Netflix's hit series about a women's prison in upstate New York, 'Orange is the New Black'.  Problem is, I always binge on it when the new season comes out then I feel depressed because I have to wait another year before it comes on again. 

I enjoy watching the opening credits as well.  Great song by Regina Spektor, called "You've Got Time", and it features many faces of different women.  At first, I thought the faces were from characters from the show, but the more I looked at them, I realized that they were not the same people.  So I did the research...

According to factodesign.com, the faces actually feature formally incarcerated women.  Great effect, I guess.  Some of the faces definitely look like they could be some hardened people.  Kind of scary, some of them.  I posted the video below of the open credits.  Watch it, or re-watch it and let me know what you think.
