When I have a studio photographic session with toddlers, I always am prepared. As gorgeous as they are and no matter how much I love photographing them (babies and children are my favourite subject) I always need to of had a coffee first! The little ones usually run around non stop and the LAST place they want to be in quietly in front of the camera.
To capture this photo, the subject was running around inspecting everything in the studio. Then I said "Oh look I think there is a puppy dog inside this camera." And click- I got the shot.
You don't have long, but its a good tool for grabbing a beautiful photograph.
