Some people have a natural instinct to smile when their picture is being taken. Others do not. I wonder if she had to ask the person in the kayak to smile for her.The person who is the focus of the picture that is being taken is not smiling, but I hope you are. (This is the naked cowboy of Times Square.)
Some photographers do have delightful smiles themselves.
I love taking pictures of kids because of their smiles.
I hope that at least some of these pictures brought a smile to your face.
