In 1975, Nicolas Nixon, a professor of photography at Mass Art, photographed his wife and her three sisters. They have continued the tradition for 36 years. When people are captured without a forced smile we get to see so much more. I love seeing the body language that shows the obvious affection these sisters have for each other through the years. For more photos and story you can go to So Bad So Good. The whole portrait collection is available in the book, Nicholas Nixon: The Brown Sisters. Thirty-Three Years.
