At the end of the movie when the cast reappear's on the boat for the final kiss, just at the part when the door opens and the camera moves in if you look very closely at the glass door you can see a reflection of the cameraman.
I believe you have your scene mixed up. There is a scene where you can see the camera man. You have to watch closely, but I believe it is the scene in which the doorman opens the door for Jack when he is on his way to dinner. You catch a glimpse of him, people have said it before in interviews with the cast.
