2 year old won't smile for pictures

My 2.4 year old DD won't let me take a picture of her. When she first learnt how to smile, she used to love posing and smiling for the camera/iPhone but she got to about 18 months then started refusing. Now she won't sit still, looks away or covers her face. If I do manage to convince her to sit still, she won't smile or actively frowns. She likes to look at photos but won't star in them! Is this normal? She's a generally happy, smily little thing but seems to hate having her photo taken.

Thanks!

Mine is the same and assumed this was normal. It is an age where they are realising they have control over things
