My college minor was photography and I know most, if not all of the tricks. It ain't photoshop. Is it really The Obamamama? Very likely. Look at the nose, the mouth, the jawline, not to mention the eys and ears. I wasn't there for the photoshoot, but outside of being an actual witness to the happy-funtime photo shoot, I could safely assume that The Obamamama was not shy in front of the camera.
