Ever think about how you and your siblings have physically changed throughout the years? If so, you'll appreciate Nicholas NIxon’s The Brown Sisters, an incredibly interesting series that reveals the gradual changes that come with time. The women in his life (or more specifically his wife and her three sisters) were photographed every year for over 30 years.
This series is an accomplishment for Nixon because, though many have attempted to document the passage of time, only a few have succeeded. Notice that in each shot, the four sisters are standing in exactly the same order.
