You can find pictures anywhere. It's simply a matter of noticing things and organizing them. You just have to care about what's around you and have a concern with humanity and the human comedy.
Now very often events are set up for photographers... The weddings are orchestrated about the photographers taking the picture, because if it hasn't been photographed it doesn't really exist.
To me, photography is an art of observation. It's about finding something interesting in an ordinary place... I've found it has little to do with the things you see and everything to do with the way you see them.
