Shallow depth of field. I'v added this frame to help over lap the pictures as you cross your eye's.
What technique did you use to capture the two photos?
May I suggest you view the updates on my later topic 3D give them what they want. I take two photos side by side. that topic will show examples of what happens when the photos are not revesed during proccessing. and the result of my corrections made on those photos. helps everything make sence:)
