That's interesting. I've noticed that over time, in pictures, people smile more. Compare pictures of people today with pictures of people from the 1800's.

That's usually because exposures took many minutes in early photography. Smiling for 5-10 minutes wasn't really possible :)

Some photographers even used metal rods to hold people's heads in place.
