Last week I tried to take my nephew's pictures. All around the situation was not easy.
It had rained the day before so the grass was wet. The only shade that we could find was a pavilion. It was sunny and taking a 2 year old's pictures in the sun as he wants to run around doesn't work so well. Lots of shadows on the face.
When you tell a young boy to stand still, his idea of standing still is for 2 seconds and then he runs. Finally some bribery was in order. When a sucker was on the line, he didn't move!
