The Minnesota History Center in St. Paul holds a reception tonight to celebrate a new exhibit and book featuring photographs of Ojibwe people in Minnesota. The author of "We Are at Home: Pictures of Ojibwe People" is historian Bruce White. His book explains that to truly understand a photo you need to know who took it and why. I asked White to select some of his favorite pictures from the book for us to talk about. The first one he chose was taken around 1900 in Grand Portage. It shows a woman in front of a tipi with a baby on her back.
