One only need consult the many intimate moments captured by James VanDerZee or Ellie Lee Weems, Florestine Perrault Collins or Addison N. Scurlock to understand a rich tradition of using studio photography to document change and celebrate special occasions in African American culture and cultures throughout the African diaspora. The Met has a repository of these images as well as photographs from the continent, as seen in their 2015 exhibition In and Out of the Studio: Photographic Portraits from West Africa.
