My son Ynigo 20 months old peek at me behind the sofa, no words yet but I got the message.
I was testing a Canon 6d Body with the Sigma A 50mm 1.4. I was trying to get action shots of my boy jumping and running then we got tired so we took a rest. Then I caught him peeking at me behind the sofa so I immediately took the shot. The best shot of the day came unplanned, I'm glad I had the camera in my hand to capture his smile telling me "Come on daddy I'm ready to play again".
