First of all, congratulations for the award...
Some time ago, History or Discovery channel, I don't remember precisely, presented a long and detailed program about The House photographers. It was a very nice program, showing a very nice and old fashioned people, able to interact continuously with POTUS, but in a delicate and elegant way. President's life is covered by his photographer minute by minute, and relationships between the two are friendly and familiar. The amount of the daily shots is really impressive, both color and b&w. They use both Canon and Nikon gear, preferring not intrusive bodies as 5D. As every real pro, familiarity and perfect integration with the equipment is definitely more important than showing up with the newest toys...
