phillips and neidichs displaying indians

I really didn't get this assignment, Phillips writes about Indians and how they are different now from when they were very primative, basically like they commercialized their heritage. And about how Neidichs pictures don't give a clear sense about how events really happened and how we don't understand them, i agree with it in that we don't really get a clear picture from how they lived with the pictures in the books, it looks historic but the facts aren't concrete.
