They are so excited to see their own picture for the first time in their whole time. They wont forget this moment for long time and they will tell others about what they have seen on that they. This is the ugly truth about humanity that lots of people around the world haven't seen a camera in their whole life!
I hope that at least they have received a copy of their own picture. They can't believe what they are seeing, its clear from their faces and their eyes.
