Giovanna - Melissa, Have you ever seen the National Geographic special "The President's Photographer"? It is such a great look into the day of Pete Souza who is Obama's photographer and that of other past photographers. The highlight of the documentary that hit home for me is when Souza realizes that when about to shoot an important moment he has to change cards in his camera...oops. It even happens to the mighty:-) Worth the watch on Netflix.
