I've just been watching some professional documentaries, and wondering how they are doing sound for interviews, particularly when there are conversations going on. Once in a while I thought I saw a lavalier mike clipped to someone's shirt, but more often not. Shotgun? Maybe. But what happens when you have, say, people sitting around a table, or a family in their living room talking to each other? Six shotgun mikes? And does a shotgun really give you the quality I've been hearing? Case in point: "45365."
