I'll have to watch the DVD again, but I believe a point made in the Adams video is that we in our Modern Society "hide" the relatives that may be mentally retarded or even just old. Whereas in the Appalachian Society all members of the family are accepted. And Shelby Lee Adams photographs all those family members. If done by an "outsider" (eg, a Walker Evans), it might appear exploitative. But done by those who grew up or live in the area, its not (or is it?).
