My thing with fans is, it's always about being really good to them and taking the time to take every picture. If there are 300 people, you should take 300 pictures - you shouldn't take 250 because then fifty people will go home sad. Why would you do that?
My dad was always taking photos of us at home, and even on set - he'd bring us along and stick us in the photos in the background. It was almost the beginning of acting for me, like, 'Hey, you go over there and play basketball in the background, and don't even think about the camera.'
