At the moment Adam is standing in the middle of a field surrounded by a large group of people. The camera Adam is using has a set field-of-view angle f, which means that if he points the camera in a direction d (measured in degrees from the x-axis) anything within the range d − f/2 to d + f/2 will be in the picture. Even with digital photography, Adam still likes to take as few pictures as possible. Given the locations of the people around Adam and the field-of-view angle, Adam would like to know the minimum number of photos he needs to take to make sure that everyone is in at least one photo. (Well, almost everyone: Some people insist on standing in a spot where they are blocked from Adam’s camera by another person. So, only the arms and top of their head will show up. There is just so much poor Adam can do. Those are the breaks.)
