Self Portrait and Casual Portrait

For something like this is there Norm for some people  and some people love doing stuff like this 

This was just any ordinary baby and mother playing that does not get any less casual than that

The reason why i chose this one is that a man that looks like been taking pictures just for a little bit is actually trying to find how to work it 

I liked this one because is that takes sand that we all known to be on the beach but its a cully looks like to be on some one that likes sand
