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".
Great shot!! My very active son is one of the hardest subjects to take a picture of and the best shots are often unplanned as well.
