I was visiting a friend and happened to have my camera along. Her daughter was reading and conversing with her mom.
I wondered whether my new zoom lens would work in tight quarters, so I tried it out and it worked well. I was able to get back far enough to capture some very expressive moments.
Sometimes these kinds of expressions are lost as people age. That's why it's so great if you can capture them when one is young.
Take lots of pictures of your kids. You won't regret it and they'll thank you for it.
