I like to smile when somebody takes a photo for me. It is nice to smile in photographs because when you look back on them later you can remember how happy you felt at the time. However, not everyone likes smiling in photographs. There are a lot of people who think smiling in photographs feels forced and they would rather look natural. For me, smiling always feels natural, so this is not a problem.

I think sometimes it can be very obvious when somebody is doing a fake smile.
