Now, go here to see photographs of the same 4 women photographed over 36 years.
Look at their body language in each picture. Who is tilted towards who? Who is touching who? What do their stances say? What do their expressions say about who they are and what they're feeling? What are their feelings towards each other?
How do the language and relationships evolve over the years? What might have been going on in their lives between each picture to cause these changes?
A brief description is below and at the link. Feel free to change the setting, time and reality.
From Nicholas Nixon: The Brown Sisters. Thirty-Three Years. Nicholas Nixon photographed his wife and her 3 sisters each year for 36 years. They were always in the same order: Heather, Mimi, Bebe and Laurie, ranging in age from 15 to 25 in the first photo.
