How about a whole department full of people, photographed in one day?
It's possible, and the results were very good indeed. We set up in an inner lobby and used some of the background to advantage, mixing it up a little with the poses and lighting. Since most of the people were computer programmers, they are not necessarily happiest in front of a camera. We had fun, keeping it lively and interesting. I think everyone got a portrait that they would be happy to share with the world.
