OH. I am all smiles and laughter and ridiculousness. Until you put a camera on me. Then I am serious and stoic. Even at my brother's wedding this summer; one of my photographers, Lavenda, shot his wedding. She had to keep reminding me to smile, which made me laugh, and then she would say, "Good job!"
Just a curious question: How long would you have to sit there as they do this? And as you mention in your description, the building, car, lighting and having you sitting there made for a great shot.
